Steganografi

Steganografi adalah seni dan ilmu menulis atau menyembunyikan pesan tersembunyi dengan suatu cara sehingga selain si pengirim dan si penerima, tidak ada seorangpun yang mengetahui atau menyadari bahwa ada suatu pesan rahasia. Sebaliknya, kriptografi menyamarkan arti dari suatu pesan, tapi tidak menyembunyikan bahwa ada suatu pesan. Kata steganografi (steganografi) berasal dari bahasa Yunani steganos, yang artinya “tersembunyi atau terselubung”, dan graphein, “menulis”.

Kini, istilah steganografi termasuk penyembunyian data digital dalam file-file komputer. Contohnya, si pengirim mulai dengan file gambar biasa, lalu mengatur warna setiap pixel ke-100 untuk menyesuaikan suatu huruf dalam alphabet (perubahannya begitu halus sehingga tidak ada seorangpun yang menyadarinya jika ia tidak benar-benar memperhatikannya).

Pada umumnya, pesan steganografi muncul dengan rupa lain seperti gambar, artikel, daftar belanjaan, atau pesan-pesan lainnya. Pesan yang tertulis ini merupakan tulisan yang menyelubungi atau menutupi. Contohnya, suatu pesan bisa disembunyikan dengan menggunakan tinta yang tidak terlihat diantara garis-garis yang kelihatan.

Teknik steganografi meliputi banyak sekali metode komunikasi untuk menyembunyikan pesan rahasia (teks atau gambar) di dalam file-file lain yang mengandung teks, image, bahkan audio tanpa menunjukkan ciri-ciri perubahan yang nyata atau terlihat dalam kualitas dan struktur dari file semula. Metode ini termasuk tinta yang tidak tampak, microdots, pengaturan kata, tanda tangan digital, jalur tersembunyi dan komunikasi spektrum lebar. Tujuan dari steganografi adalah merahasiakan atau menyembunyikan keberadaan dari sebuah pesan tersembunyi atau sebuah informasi. Dalam prakteknya kebanyakan diselesaikan dengan membuat perubahan tipis terhadap data digital lain yang isinya tidak akan menarik perhatian dari penyerang potensial, sebagai contoh sebuah gambar yang terlihat tidak berbahaya. Perubahan ini bergantung pada kunci (sama pada kriptografi) dan pesan untuk disembunyikan. Orang yang menerima gambar kemudian dapat menyimpulkan informasi terselubung dengan cara mengganti kunci yang benar ke dalam algoritma yang digunakan.


Pada metode steganografi cara ini sangat berguna jika digunakan pada cara steganografi komputer karena banyak format file digital yang dapat dijadikan media untuk menyembunyikan pesan. Format yang biasa digunakan diantaranya:

Format image : bitmap (bmp), gif, pcx, jpeg, dll.
Format audio : wav, voc, mp3, dll.
Format lain : teks file, html, pdf, dll.

Kelebihan steganografi daripada kriptografi adalah pesan-pesannya tidak menarik perhatian orang lain. Pesan-pesan berkode dalam kriptografi yang tidak disembunyikan, walaupun tidak dapat dipecahkan, akan menimbulkan kecurigaan. Seringkali, steganografi dan kriptografi digunakan secara bersamaan untuk menjamin keamanan pesan rahasianya.

Sebuah pesan steganografi (plaintext), biasanya pertama-tama dienkripsikan dengan beberapa arti tradisional, yang menghasilkan ciphertext. Kemudian, covertext dimodifikasi dalam beberapa cara sehingga berisi ciphertext, yang menghasilkan stegotext. Contohnya, ukuran huruf, ukuran spasi, jenis huruf, atau karakteristik covertext lainnya dapat dimanipulasi untuk membawa pesan tersembunyi; hanya penerima (yang harus mengetahui teknik yang digunakan) dapat membuka pesan dan mendekripsikannya.

How To Block Websties Without Software

How To Block Websties Without Software, block websites

 Steps:

1] Browse C:\WINDOWS\system32\drivers\etc
2] Find the file named "HOSTS"
3] Open it in notepad
4] Under "127.0.0.1 localhost" Add 127.0.0.2 www.sitenameyouwantblocked.com , and that site will no longer be accessable.
5] Done!

-So-

127.0.0.1 localhost
127.0.0.2 www.blockedsite.com

-->www.blockedsite.com is now unaccessable<--


For every site after that you want to add, just add "1" to the last number in the internal ip (127.0.0.2) and then the addy like before.

IE: 127.0.0.3 www.blablabla.com
127.0.0.4 www.blablabla.com
127.0.0.5 www.blablabla.com

etc

Tutorial Get the serial number you need

Get the serial number you need ! (For Certain Things)

* Go to Google.

* In the search field type: "Product name" 94FBR

* Where, "Product Name" is the name of the item you want to find the serial number for.

* And voila - there you go - the serial number you needed.

HOW DOES THIS WORK?

Quite simple really. 94FBR is part of a Office 2000 Pro cd key that is widely distributed as it bypasses the activation requirements of Office 2K Pro. By searching for the product name and 94fbr, you guarantee two things. 1) The pages that are returned are pages dealing specifically with the product you're wanting a serial for. 2) Because 94FBR is part of a serial number, and only part of a serial number, you guarantee that any page being returned is a serial number list page.

See these example searches:

"Photoshop 7" 94FBR
"Age of Mythology" 94FBR
"Nero Burning Rom 5.5" 94FBR

1. Introduction
2. The Binary System
3. Converting Binary to ASCII (Text)

Introduction:
We’ve all seen binary code. We’ve come to think of them as a bunch of ones and zeroes in long strings…
010010101010101001101011

But these ones and zeroes can also represent decimal numbers. First off, I will show you how to read these numbers as the decimal numbers we’re used to in our daily life. Then, I will show you how to use those numbers and your keypad to translate them into text. Note that your computer doesn’t use the decimal system, so technically, when it converts binary to text, it doesn’t go through the process I will show you. This is just a divertive way of explaining you how the binary system works.

The Binary System:
Here’s a simple example of binary:
10101

Let’s think of the example above as empty slots:
_ _ _ _ _

First off, you read binary from right-to-left. It’s just the way it’s designed. The first slot from the right represents a value of one, the second from the right a value of two, the third from the right a value of four, the fourth from the right a value of eight, the fifth from the right a value of sixteen, and the cycle continues by multiples of 2. This will never change.

By putting a 1 or a 0 in those slots you are either saying you want to corresponding value that’s attached to that slot or you don’t. A 1 means yes, and a 0 means no. For example, putting a zero in the first slot from the right, but a 1 in the second slot from the right means you want a two, but not a one:
_ _ _ 1 0

As such, the number above equals to a decimal value of two.

As an example, let’s say you want to represent eight in binary form. Well, thinking about the slots, you want the first slot to be 0 because you don’t want a one, you want the second slot to also be 0 because you don’t want a two, you want the third slot to also to be 0 because you don’t want a four, but you want the fifth slot to be 1 because you want a value of eight. As such, eight in binary form is:
1 0 0 0 (or simply 1000 without those underlines)

Now it is important to note that the amount of zeroes that precede the first value of one from the left is unimportant. So for example:
1 0 0 0 is the same as 0 0 0 1 0 0 0 (1000 = 000100)

To get it cleared up, here’s another example:
0 1 is the same as 1


Exercises: What do the following equal in decimal terms?
a) 100
b] 000100
c) 100000
d) 0010

Answers:
a) 4
b] 4
c) 32
d) 2

If you got the answers above right, then you pretty much understand the basics of binary.
Let’s now understand how to get the corresponding decimal values to the numbers which are not multiples of 2.

To get the total value of a binary number, add the values corresponding to each slot. So, for example, three in binary would be:
11

The above corresponds to three because if you add the total values of all the slots, that is to say a one from the slot to the right, and a two from the second slot to the right, then it equals three.

As another example, let’s say you want to represent 5 in binary terms. Then you would need a value of one to be added to a value of four, and you would not want a value of two:
101 [Reading from the right: 1(one) + 0(two) + 1(four) = five]

Here’s an additional example:
001011 [Reading from the right: 1(one) + 1(two) + 0(four) + 1(eight) + 0(sixteen) + 0(thirty-two) = eleven)



Exercises: What do the following equal in decimal terms?
a) 11011
b] 110
c) 010101
d) 10110

Answers:
a) 27
b] 6
c) 21
d) 22

If you got the above questions correct [without cheating], then you essentially understand the binary system. Understanding the binary system was the hard part. What follows is pretty easy.

3. Converting Binary to ASCII (Text)
ASCII is essentially the letters, numbers and symbols that are stored in our computers through the use of fonts. When the keyboard relays the buttons you pressed, it sends in a code which is then converted to the ASCII equivalent of “k” or “5” or whatever key you pressed.

Here’s an example of a message “hidden” in binary text:
0100100001100101011011000110110001101111

Now there are only so many letters, numbers and symbols stored for ASCII. Having sets of 8 digits for their binary equivalent is more than enough to represent all of these letters and the like. As such, all strings that represent text like in the above are separated into bits of 8 for simplicity:
01001000 01100101 01101100 01101100 01101111

Okay, so our example message was separated into 8 digit strings. The decimal value for each of these strings in the example was calculated for you.
01001000 = 72
01100101 = 101
01101100 = 108
01101100 = 108
01101111 = 111

The result was 72,101,108,108,111. Now, there is something called the ASCII table. It essentially corresponds to the binary numbers from yore to the equivalent letters/symbols/numbers. But since we found the decimal values of these binary strings, we can use a major shortcut.

By pressing ALT + [The Number], you will get the ASCII equivalent of that number. For example, by pressing the ALT key and at then (while keeping it down) the numbers 72 in any text editor, you will get the corresponding “H” to show up.

Let’s do so for the entire example message:
72 = H
101 = e
108 = l
108 = l
111 = o

So the entire “hidden” message translates to “Hello”.


Exercise: Decode the following message
01000011011011110110111001100111011100100110000101110100011101010110110001100001
011101000
1101001011011110110111001110011 00100001

Hint: The first step on your way to decoding the message (separated into bytes for you)
01000011 01101111 01101110 01100111 01110010 01100001 01110100 01110101 01101100 01100001 01110100 01101001 01101111 01101110 01110011 00100001

01101111 = 111

The result was 72,101,108,108,111. Now, there is something called the ASCII table. It essentially corresponds to the binary numbers from yore to the equivalent letters/symbols/numbers. But since we found the decimal values of these binary strings, we can use a major shortcut.

By pressing ALT + [The Number], you will get the ASCII equivalent of that number. For example, by pressing the ALT key and at then (while keeping it down) the numbers 72 in any text editor, you will get the corresponding “H” to show up.

Let’s do so for the entire example message:
72 = H
101 = e
108 = l
108 = l
111 = o

So the entire “hidden” message translates to “Hello”.


Exercise: Decode the following message
010000110110111101101110011001110111001001100001011101000111010101101100011000010111010001
101001011011110110111001110011 00100001

Hint: The first step on your way to decoding the message (separated into bytes for you)
01000011 01101111 01101110 01100111 01110010 01100001 01110100 01110101 01101100 01100001 01110100 01101001 01101111 01101110 01110011 00100001

PC Maintenance Guide

PC Maintenance Guide

"Take good care of your PC, and it will take good care of you."

It's a nice sentiment, but reality is more like "Take good care of your PC, and it won't crash, lose your data, and cost you your job--probably." Follow these steps to stop PC problems before they stop you.

Your PC's two mortal enemies are heat and moisture. Excess heat accelerates the deterioration of the delicate circuits in your system. The most common causes of overheating are dust and dirt: Clogged vents and CPU cooling fans can keep heat-dissipating air from moving through the case, and even a thin coating of dust or dirt can raise the temperature of your machine's components.

Any grime, but especially the residue of cigarette smoke, can corrode exposed metal contacts. That's why it pays to keep your system clean, inside and out.

If your PC resides in a relatively clean, climate-controlled environment, an annual cleaning should be sufficient. But in most real-world locations, such as dusty offices or shop floors, your system may need a cleaning every few months.

All you need are lint-free wipes, a can of compressed air, a few drops of a mild cleaning solution such as Formula 409 or Simple Green in a bowl of water, and an antistatic wrist strap to protect your system when you clean inside the case.

Think Outside the Box

Before you get started cleaning, check around your PC for anything nearby that could raise its temperature (such as a heating duct or sunshine coming through a window). Also clear away anything that might fall on it or make it dirty, such as a bookcase or houseplants.

Always turn off and unplug the system before you clean any of its components. Never apply any liquid directly to a component. Spray or pour the liquid on a lint-free cloth, and wipe the PC with the cloth.

Clean the case: Wipe the case and clear its ventilation ports of any obstructions. Compressed air is great for this, but don't blow dust into the PC or its optical and floppy drives. Keep all cables firmly attached to their connectors on the case.

Maintain your mechanical mouse: When a nonoptical mouse gets dirty, the pointer moves erratically. Unscrew the ring on the bottom of the unit and remove the ball. Then scrape the accumulated gunk off the two plastic rollers that are set 90 degrees apart inside the ball's housing.

Keep a neat keyboard: Turn the keyboard upside down and shake it to clear the crumbs from between the keys. If that doesn't suffice, blast it (briefly) with compressed air. If your keys stick or your keyboard is really dirty, pry the keys off for easier cleaning. Computer shops have special tools for removing keys, but you can also pop them off by using two pencils with broken tips as jumbo tweezers--just be sure to use a soft touch.

Make your monitor sparkle: Wipe the monitor case and clear its vents of obstructions, without pushing dust into the unit. Clean the screen with a standard glass cleaner and a lint-free cloth. If your monitor has a degauss button (look for a small magnet icon), push it to clear magnetic interference. Many LCDs can be cleaned with isopropyl alcohol; check with your LCD manufacturer. Wipe your LCD lightly: The underlying glass is fragile.

Check your power protection: Reseat the cables plugged into your surge protector. Check the unit's warning indicator, if it has one. Surge protectors may power your PC even after being compromised by a voltage spike (making your system susceptible to a second spike). If your power protector doesn't have a warning indicator and your area suffers frequent power outages, replace it with one that has such an indicator and is UL 1449 certified.

Swipe your CD and DVD media: Gently wipe each disc with a moistened, soft cloth. Use a motion that starts at the center of the disc and then moves outward toward the edge. Never wipe a disc in a circular motion.

Inside the Box

Before cracking open the case, turn off the power and unplug your PC. Ground yourself before you touch anything inside to avoid destroying your circuitry with a static charge. If you don't have a grounding wrist strap, you can ground yourself by touching any of various household objects, such as a water pipe, a lamp, or another grounded electrical device. Be sure to unplug the power cord before you open the case.

Use antistatic wipes to remove dust from inside the case. Avoid touching any circuit-board surfaces. Pay close attention to the power-supply fan, as well as to the case and to CPU fans, if you have them. Spray these components with a blast of compressed air to loosen dust; but to remove the dust rather than rearrange it, you should use a small vacuum.

If your PC is more than four years old, or if the expansion cards plugged into its motherboard are exceptionally dirty, remove each card, clean its contacts with isopropyl alcohol, and reseat it. If your system is less than a couple years old, however, just make sure each card is firmly seated by pressing gently downward on its top edge while not touching its face. Likewise, check your power connectors, EIDE connectors, and other internal cables for a snug fit.

While you have the case open, familiarize yourself with the CMOS battery on the motherboard. For its location, check the motherboard manual. If your PC is more than four or five years old, the CMOS battery may need to be replaced. (A system clock that loses time is one indicator of a dying CMOS battery.)

Look for Trouble

Give your PC a periodic checkup with a good hardware diagnostic utility. Two excellent choices are Sandra Standard from SiSoftware and #1-TuffTest-Lite from #1-PC Diagnostics. Download the free version of Sandra (the full version of the application costs $35) or to download #1-TuffTest-Lite (the fully functional version is $10).

Adding and removing system components leaves orphaned entries in the Windows Registry. This can increase the time your PC takes to boot and can slow system performance. Many shareware utilities are designed to clean the Registry.

Windows stores files on a hard drive in rows of contiguous segments, but over time the disk fills and segments become scattered, so they take longer to access. To keep your drive shipshape, run Windows' Disk Defragmenter utility. Click Start, Programs (All Programs in XP), Accessories, System Tools, Disk Defragmenter. If your drive is heavily fragmented, you could boost performance. Defragging may take hours, however. Disable your screen saver and other automatic programs beforehand to keep the defrag from restarting every few minutes.

Disk Defragmenter won't defragment the file on your hard drive that holds overflow data from system memory (also known as the swap file). Since the swap file is frequently accessed, defragmenting it can give your PC more pep. You can defragment your swap file by using a utility such as the SpeedDisk program included with Norton SystemWorks 2004, but there's a way to reset it in Windows.

In Windows XP, right-click My Computer and choose Properties. Click Advanced, and then choose the Settings button under Performance. Click Advanced again and the Change button under Virtual Memory. Select another drive or partition, set your swap file size, and click OK.

If you have only one partition and no way to create a second one, and you have at least 256MB of RAM, disable the swap file rather than moving it: Select "No paging file" in the Virtual Memory settings. If you have trouble booting, start Windows in Safe Mode and re-enable this option.

Hard-Drive Checkup
Windows XP offers a rudimentary evaluation of your hard disk's health with its error-checking utility: Right-click the drive's icon in Windows Explorer and select Properties, Tools, Check Now. (Windows can fix errors and recover bad sectors automatically if you wish.) If the check discovers a few file errors, don't worry, but if it comes up with hundreds of errors, the drive could be in trouble.

To conduct a more thorough examination, download Panterasoft's free HDD Health utility, which monitors hard-drive performance and warns of impending disaster:

The program works only with drives that support S.M.A.R.T technology, but nearly all drives released since 2000 are S.M.A.R.T.-compliant.

Many hardware and software designers humbly assume you want their program running on your PC all the time, so they tell Windows to load the application at startup (hence, the ever-growing string of icons in your system tray). These programs eat up system resources and make hardware conflicts and compatibility problems more likely. To prevent them from launching, just click Start, Run, type "msconfig" and press Enter. The programs listed under the Startup tab are set to start along with Windows. Uncheck the box at the left of each undesirable program to prevent it from starting automatically.

Four Tips for Longer PC Life

1. Keep your PC in a smoke-free environment. Tobacco smoke can damage delicate contacts and circuits.

2. Leave your PC running. Powering up from a cold state is one of the most stressful things you can do to your system's components. If you don't want to leave your PC running all the time, use Windows' Power Management settings to put your machine into hibernation rather than completely shutting down. In Windows XP, right-click the desktop and select Properties. Click the Screen Saver tab and select the Power button. Choose the Hibernate tab to ensure that hibernation is enabled, and then select a time beneath "System hibernates" under the Power Schemes tab. (Note that this option is not available on all PCs.) Computers running older versions of Windows may or may not provide similar power-management features. Look under the Power Management icon (Power Options in Windows 2000) in Control Panel to evaluate your machine's capabilities.

3. Don't leave your monitor running. The best way to extend your display's life is to shut it off when it's not in use.

4. Avoid jostling the PC. Whenever you move your system, even if it's just across the desktop, make sure the machine is shut down and unplugged.

Firefox Speed Tweaks

Yes, firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more?

That's the beauty of this program being open source.
Here's what you do:
In the URL bar, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox.

Note that these are what I’ve found to REALLY speed up my Firefox significantly - and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections - I mean with as much concurrent requests we’re going to open up with pipelining… lol… you’d better have a big connection.

Double Click on the following settins and put in the numbers below - for the true / false booleans - they’ll change when you double click.

Code:
browser.tabs.showSingleWindowModePrefs – true
network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true
network.http.pipelining.maxrequests – 100
network.http.proxy.pipelining – true
network.http.request.timeout – 300


One more thing… Right-click somewhere on that screen and add a NEW -> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0”. This value is the amount of time the browser waits before it acts on information it receives. Since you’re broadband - it shouldn’t have to wait.

Now you should notice you’re loading pages MUCH faster now!

23 Ways To Speed WinXP, Not only Defrag

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.
1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Hide Drives and Partitions

Hide Drives and Partitions

Do you have data on a partition or hard drive that you don't want tampered with or easily accessible to other users? Well, you can hide any drive/partition in Windows XP, NT, and 2000. That means that they won't show up in Explorer or My Computer.

If you want access to that drive from your user account you should create a desktop shortcut before proceeding. Once hidden, you can still access by typing the drive letter and a colon in Start/Run—for example, "D:" will bring up a folder of the contents on your D drive.

The easiest way with Win XP is to use the TweakUI power toy from Mcft. Go to Start/Run and type in "tweakui" (without the quotes).

Go to My Computer/Drives and uncheck the drive/partition(s) you want hidden. Click "Apply" or "OK" when finished.

If you have XP but not Tweak UI you can download it here...
http://www.Mcft.com/windowsxp/downloads/powertoys/xppowertoys.mspx

For Win NT, 2000, and XP you can use the following Registry edit:

*Be sure to back up the Registry before proceeding
http://www.worldstart.com/tips/tips.php/401

Open the Registry Editor by going to Start/Run and typing in "regedit" (without the quotes). Find your way to...

HKEY_CURRENT_USER\Software\Mcft\Windows\CurrentVersion\Policies

Click on "Explorer".

Double-click the "NoDrives" key in the right column. If you don't find a "NoDrives" registry key, just right-click in the right pane and choose "New/DWORD Value" then name the key "NoDrives".

You'll see a value like "0000 00 00 00 00". This is where the fun starts. The four sets of double zeros (after the "0000") are where you'll enter the values for the drive/partitions. Now, stay with me on this—it's not as complicated as it sounds:

The first column is for drives A-H, the second for I-P, the third for Q-X, and the fourth for Y-Z.

The values for each drive are as follows:

1 - A I Q Y
2 - B J R Z
4 - C K S
8 - D L T
16 - E M U
32 - F N V
64 - G O W
80 - H P X

So, let's say you want to hide drive D. In the first column you would put "08". For drive K you would put "04" in the second column.

But what if you want to hide more than one drive in a column? Simply add the values together: D+E = 8+16 = 24. So in the first column you would put "24".

Still baffled? If you have XP then go get TweakUI and save yourself the math.

Whichever method you use, you can rest easy knowing that the files on that drive or partition are less accessible to other users.

How To Boot Xp Faster

First of all, this tweak only apply to those who only have one HDD on their primary IDE channel (nothing else on device 0 or 1) and a CD-ROM and/or DVD-ROM on the secondary IDE channel. Each time you boot Windows XP, there's an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (%SystemRoot%Prefetch) and there's no need to erease any other files as the new prefetch option in XP really improves loading time of installed programs. We only want WindowsXP to boot faster and not decrease its performance. Thanks to Rod Cahoon (for the prefetch automation process...with a minor change of mine) and Zeb for the IDE Channel tweak as those two tricks, coupled together with a little modification, result in an EXTREMELY fast bootup:

1. Open notepad.exe, type "del c:windowsprefetch tosboot-*.* /q" (without the quotes) & save as "ntosboot.bat" in c:
2. From the Start menu, select "Run..." & type "gpedit.msc".
3. Double click "Windows Settings" under "Computer Configuration" and double click again on "Shutdown" in the right window.
4. In the new window, click "add", "Browse", locate your "ntosboot.bat" file & click "Open".
5. Click "OK", "Apply" & "OK" once again to exit.
6. From the Start menu, select "Run..." & type "devmgmt.msc".
7. Double click on "IDE ATA/ATAPI controllers"
8. Right click on "Primary IDE Channel" and select "Properties".
9. Select the "Advanced Settings" tab then on the device 0 or 1 that doesn't have 'device type' greyed out select 'none' instead of 'autodetect' & click "OK".
10. Right click on "Secondary IDE channel", select "Properties" and repeat step 9.
11. Reboot your computer.

WindowsXP should now boot REALLY faster.

Steps to Clean Install XP

Steps to Clean Install XP

If the above instructions for configuring your system to boot from CD
or you have acquired the necessary boot floppy/floppies; you can now
boot the computer and follow the on screen prompts. Have your Product Key
available, typical install is around 30 minutes. If setup seems to hang,
wait at least 10 minutes + before restarting system. You should experience
momentary screen blackouts.

1. Power on the computer. Press the Pause/Break key as soon as you see
text on the screen. [If you currently are running in an OS of any flavor,
insert XP CD and restart computer. Skip to #3 if system is configured
to boot from CD.]


2. Insert XP CD into CD drive. Press ENTER to resume booting from the XP CD.
(BIOS must support booting from CD and boot order must be set so CD
boots before hard drive. If computer does not support booting from CD
go to 2a for floppy install).

2a. Floppy install: Boot from Win98/Me/Special XP install floppy
disk with smartdrv.exe added to the boot disk; or the Win XP set
of 6 floppy disks.

3. Look for message "booting from CD" usually located at the bottom of
the screen. If you have a factory splash screen, press ESC to unload
it.

3a. Floppy install: From the A Prompt; A:\type: smartdrv.exe. then
press ENTER. If you are using the XP boot floppy setup disks skip
to step #5.

4. Press any Key when you see the prompt to "Press Any Key"

4a. Floppy install: CD to the location of the CD-ROM drive with the
XP setup files; CD to the i386 folder where you will type: winnt.exe
to start setup.

5. Setup will start copying files, if you need to install any third
- party or RAID drivers press F6 at this time. the copying of files
can take awhile.

6. Next you will get the option to repair or enter setup, choose to
enter setup. Press ENTER. To see images full size, place mouse cursor
over image and click/double click or press the left button and open.

7. Press F8 if you agree to the license.

8. Setup will scan for previous Windows installations

9. If you are using the upgrade version of XP on a computer without
any version of Windows currently installed, this is where you will
replace the XP CD with your qualifying CD, XP setup will scan the
qualifying CD and instruct you to replace it with the XP CD to continue
XP setup; otherwise, you will not see this screen. Clean install
qualifying media can be any of the following Win NT3.51, 4.0, 2000,
Win 95, 98, Me. 10. Choose the location to install.

10a If this is a clean hard drive, you can choose to create a
partition in the un-partitioned space. At this point, you can allow
Setup to use all the space or set a size for the partition.

10b If the hard drive or partition has a previous installation of
XP you want to remove, choose to delete the partition by pressing
"D". You will then be prompted to create a new partition in the
empty space. This will remove all data from the delete space.

10c If you intend to use multiple partitions, or dual boot, this is
where you specify the size of the boot partition and or setup
location for XP. If you are planning to dual boot XP, I would
create a small 100 meg DOS partition for the first primary partition,
then an 8 to 10 gig partition for XP. You can partition and format
the remaining space after XP is setup from Disk Manager. If you do not
intend to dual boot, you can either use all the un-partitioned space,
or create an 8 to 10 gig partition for XP and leave the rest free to
partition later.

Note: If a fat32 partition larger than 32 gigabyte is desired, the
hard drive or partition will need to be created before running XP
setup. XP will not create a fat 32 partition larger than 32 gig, but
will support one previously created.

11. Choose the file system from this screen. If dual booting and you
created the small 100 meg partition, make it a fat partition. NTFS is
configured at the optimal file size during the initial setup. See this
link for more on NTFS

12. If you have more that one partition or hard drive on your system,
make sure you are formatting the correct partition/drive.

30 days of installing XP, but you do not ever have to register,
Registration is completely optional and if you do not register, no
personal information will be transmitted during activation. If you
register, then activation will transmit that information along with
the activation. The first Activation is usually done over the internet
if the computer is connected to the internet, otherwise, it can be
accomplished by copying the alphanumeric string from the activation
screen and make a phone call to the on screen supplied phone number.
The activation center will then give you a slightly longer number to
input into for activation. I suggest you do not activate immediately
in case you need to make hard ware changes, or install to a different
system within the thirty days, and you will be reminded on boot up
until you do.

Blaster worm warning: Do not immediately activate over the internet
when asked, enable the XP firewall before connecting to the internet.
You can activate after the firewall is enabled.

Best Keyboard Shortcuts

Getting used to using your keyboard exclusively and leaving your mouse behind will make you much more efficient at performing any task on any Windows system. I use the following keyboard shortcuts every day:

Windows key + R = Run menu

This is usually followed by:
cmd = Command Prompt
iexplore + "web address" = Internet Explorer
compmgmt.msc = Computer Management
dhcpmgmt.msc = DHCP Management
dnsmgmt.msc = DNS Management
services.msc = Services
eventvwr = Event Viewer
dsa.msc = Active Directory Users and Computers
dssite.msc = Active Directory Sites and Services
Windows key + E = Explorer

ALT + Tab = Switch between windows

ALT, Space, X = Maximize window

CTRL + Shift + Esc = Task Manager

Windows key + Break = System properties

Windows key + F = Search

Windows key + D = Hide/Display all windows

CTRL + C = copy

CTRL + X = cut

CTRL + V = paste

Also don't forget about the "Right-click" key next to the right Windows key on your keyboard. Using the arrows and that key can get just about anything done once you've opened up any program.
