How to hide a file in image

How to hide a file in image -
1. Gather the file you wish to bind, and the image file, and place them in a folder. 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 there.
b) Leave the file extension as is, right click, open with WinRar and your file is there

Speed Up Shutdown Time for WinXP

XP clear your paging file (pagefile.sys) of its contents whenever you shut down for security reasons. Your paging file is used to store temporary files and data, sensitive information, such as unencrypted passwords etc.
So if extreme security isn't required, then shut down XP without clearing your paging file by :-
1. Run the Registry Editor ( type regedit in Run and enter)
2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. Change the value of ClearPageFileAtShutdown to 0.
4.Close the Registry and restart your computer.
Now on while turning off XP , the paging file won't be cleared, and shut down will be more quickly.
