HIDE ANY FILE IN .JPG(image) FILE:

1. Gather the file you wish to bind, and the image file, and place them in a folder. For the sake of this demonstration, I will be using C:\New Folder-The image will hereby be referred to in all examples as fluffy.jpg-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typingcd location [ex: cd C:\New Folder]
5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)
Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.
In order to view/extract your file, there are two options that you can take
a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is thereb) Leave the file extension as is, right click, open with WinRar and your file is there

Remove Windows Messenger

It seems that a lot of people are interested in removing Windows Messenger for some reason, though I strongly recommend against this: In Windows XP, Windows Messenger will be the hub of your connection to the .NET world, and now that this feature is part of Windows, I think we're going to see a lot of .NET Passport-enabled Web sites appearing as well. But if you can't stand the little app, there are a couple of ways to get rid of it, and ensure that it doesn't pop up every time you boot into XP. The best way simply utilizes the previous tip:
If you'd like Windows Messenger to show up in the list of programs you can add and remove from Windows, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open sysoc.inf (see the previous tip for more information about this file). You'll see a line that reads:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
Change this to the following and Windows Messenger will appear in Add or Remove Programs, then Add/Remove Windows Components, then , and you can remove it for good:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,7

Add/Remove optional features of Windows XP

To dramatically expand the list of applications you can remove from Windows XP after installation, navigate to C:\WINDOWS\inf (substituting the correct drive letter for your version of Windows) and open the sysoc.inf file. Under Windows XP Professional Edition RC1, this file will resemble the following by default:
[Version] Signature = "$Windows NT$"DriverVer=06/26/2001,5.1.2505.0
[Components]NtComponents=ntoc.dll,NtOcSetupProc,,4WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7Display=desk.cpl,DisplayOcSetupProc,,7Fax=fxsocm.dll,FaxOcmSetupProc,fxsocm.inf,,7NetOC=netoc.dll,NetOcSetupProc,netoc.inf,,7iis=iis.dll,OcEntry,iis.inf,,7com=comsetup.dll,OcEntry,comnt5.inf,hide,7dtc=msdtcstp.dll,OcEntry,dtcnt5.inf,hide,7IndexSrv_System = setupqry.dll,IndexSrv,setupqry.inf,,7TerminalServer=TsOc.dll, HydraOc, TsOc.inf,hide,2msmq=msmqocm.dll,MsmqOcm,msmqocm.inf,,6ims=imsinsnt.dll,OcEntry,ims.inf,,7fp_extensions=fp40ext.dll,FrontPage4Extensions,fp40ext.inf,,7AutoUpdate=ocgen.dll,OcEntry,au.inf,hide,7msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7msnexplr=ocmsn.dll,OcEntry,msnmsn.inf,,7smarttgs=ocgen.dll,OcEntry,msnsl.inf,,7RootAutoUpdate=ocgen.dll,OcEntry,rootau.inf,,7Games=ocgen.dll,OcEntry,games.inf,,7AccessUtil=ocgen.dll,OcEntry,accessor.inf,,7CommApps=ocgen.dll,OcEntry,communic.inf,HIDE,7MultiM=ocgen.dll,OcEntry,multimed.inf,HIDE,7AccessOpt=ocgen.dll,OcEntry,optional.inf,HIDE,7Pinball=ocgen.dll,OcEntry,pinball.inf,HIDE,7MSWordPad=ocgen.dll,OcEntry,wordpad.inf,HIDE,7ZoneGames=zoneoc.dll,ZoneSetupProc,igames.inf,,7
[Global]WindowTitle=%WindowTitle%WindowTitle.StandAlone="*"
The entries that include the text hide or HIDE will not show up in Add/Remove Windows Components by default. To fix this, do a global search and replace for ,hide and change each instance of this to , (a comma). Then, save the file, relaunch Add/Remove Windows Components, and tweak the installed applications to your heart's content.
Cool, eh? There are even more new options now under "Accessories and Utilities" too.

Change the location of the My Music or My Pictures folders

In Windows 2000, Microsoft added the ability to right-click the My Documents folder and choose a new location for that folder in the shell. With Windows XP, Microsoft has elevated the My Music and My Pictures folders to the same "special shell folder" status of My Documents, but they never added a similar (and simple) method for changing those folder's locations. However, it is actually pretty easy to change the location of these folders, using the following method.
Open a My Computer window and navigate to the location where you'd like My Music (or My Pictures) to reside. Then, open the My Documents folder in a different window. Drag the My Music (or My Pictures) folder to the other window, and Windows XP will update all of the references to that folder to the new location, including the Start menu.
Or use Tweak UI

Add album art to any music folder

One of the coolest new features in Windows XP is its album thumbnail generator, which automatically places the appropriate album cover art on the folder to which you are copying music (generally in WMA format). But what about those people that have already copied their CDs to the hard drive using MP3 format? You can download album cover art from sites such as cdnow.com or amguide.com, and then use the new Windows XP folder customize feature to display the proper image for each folder. But this takes time--you have to manually edit the folder properties for every single folder--and you will lose customizations if you have to reinstall the OS. There's an excellent fix, however.
When you download the album cover art from the Web, just save the images as folder.jpg each time and place them in the appropriate folder. Then, Windows XP will automatically use that image as the thumbnail for that folder and, best of all, will use that image in Windows Media Player for Windows XP (MPXP) if you choose to display album cover art instead of a visualization. And the folder customization is automatic, so it survives an OS reinstallation as well. Your music folders never looked so good!
Album cover art makes music folder thumbnails look better than ever!

Display Hibernate Option on the Shut Down dialog

For some reason, Hibernate may not be available from the default Shut Down dialog. But you can enable it simply enough, by holding down the SHIFT key while the dialog is visible. Now you see it, now you don't!

Stop Windows Messenger from Auto-Starting

If you're not a big fan of Windows Messenger simply delete the following Registry Key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\MSMSGS

Enable ClearType on the Welcome Screen!

As laptop users and other LCD owners are quickly realizing, Microsoft's ClearType technology in Windows XP really makes a big difference for readability. But the this feature is enabled on a per-user basis in Windows XP, so you can't see the effect on the Welcome screen; it only appears after you logon.
But you can fix that. Fire up the Registry Editor and look for the following keys:
(default user) HKEY_USERS \ .Default \ Control Panel \ Desktop \ FontSmoothing (String Value)HKEY_USERS \ .Default \ Control Panel \ Desktop \ FontSmoothingType (Hexadecimal DWORD Value)
Make sure both of these values are set to 2 and you'll have ClearType enabled on the Welcome screen and on each new user by default.

Remove the Desktop version text
During the Windows XP beta, you will see text in the lower right corner of the screen that says Windows XP Professional, Evaluation Copy. Build 2462 or similar. A lot of people would like to remove this text for some reason, and while it's possible to do so, the cure is more damaging than the problem, in my opinion. So the following step will remove this text, but you'll lose a lot of the nice graphical effects that come in Windows XP, such as the see-through icon text.
To remove the desktop version text, open Display Properties (right-click the desktop, then choose Properties) and navigate to the Desktop page. Click Customize Desktop and then choose the Web page in the resulting dialog. On this page, check the option titled Lock desktop items. Click OK to close the dialog, and then OK to close Display Properties. The text disappears. But now the rest of your system is really ugly. You can reverse the process by unchecking Lock desktop items.
There's also a shortcut for this process: Just right-click the desktop and choose Arrange by then Lock Web Icons on the Desktop.

Do an unattended installation

The Windows XP Setup routine is much nicer than that in Windows 2000 or Windows Me, but it's still an hour-long process that forces you to sit in front of your computer for an hour, answering dialog boxes and typing in product keys. But Windows XP picks up one of the more useful features from Windows 2000, the ability to do an unattended installation, so you can simply prepare a script that will answer all those dialogs for you and let you spend some quality time with your family.I've written about Windows 2000 unattended installations and the process is pretty much identical on Windows XP, so please read that article carefully before proceeding. And you need to be aware that this feature is designed for a standalone Windows XP system: If you want to dual-boot Windows XP with another OS, you're going to have to go through the interactive Setup just like everyone else: An unattended install will wipe out your hard drive and install only Windows XP, usually.
To perform an unattended installation, you just need to work with the Setup Manager, which is located on the Windows XP CD-ROM in D:\SupportTools\DEPLOY.CAB by default: Extract the contents of this file and you'll find a number of useful tools and help files; the one we're interested in is named setupmgr.exe. This is a very simple wizard application that will walk you through the process of creating an answer file called winnt.sif that can be used to guide Windows XP Setup through the unattended installation.
One final tip: There's one thing that Setup Manager doesn't add: Your product key. However, you can add this to the unattend.txt file manually. Simply open the file in Notepad and add the following line under the [UserData] section:
ProductID=RK7J8-2PGYQ-P47VV-V6PMB-F6XPQ
(This is a 60 day CD key)
Then, just copy winnt.sif to a floppy, put your Windows XP CD-ROM in the CD drive, and reboot: When the CD auto-boots, it will look for the unattend.txt file in A: automatically, and use it to answer the Setup questions if it's there.
Finally, please remember that this will wipe out your system! Back up first, and spend some time with the help files in DEPLOY.CAB before proceeding.

Speed up Internet Explorer 6 Favorites

For some reason, the Favorites menu in IE 6 seems to slow down dramatically sometimes--I've noticed this happens when you install Tweak UI 1.33, for example, and when you use the preview tip to speed up the Start menu. But here's a fix for the problem that does work, though it's unclear why:Just open a command line window (Start button -> Run -> cmd) and type sfc, then hit ENTER. This command line runs the System File Checker, which performs a number of services, all of which are completely unrelated to IE 6. But there you go: It works.
