Automatically defrag drives with a new context menu

Create a new Registry import file named context_defrag.inf in Notepad (be sure to save with it with the Save as type set to All Files and not Text Documents) and place the following text inside:

; context_defrag.INF

; Adds Defrag to the right click context menu in Windows XP

[version]
signature="$CHICAGO$"

[DefaultInstall]
AddReg=AddMe

[AddMe]

HKCR,"Drive\Shell\Defrag\command",,,"DEFRAG.EXE %1"

Then, right-click and choose Install. This will add a context menu to XP that allows you to automatically defrag drives, using the command line version of the built-in defragmentation utility. To use it, navigate to a drive in My Computer, right-click, and choose Defrag. A command line window will appear, and that drive will be defragged. When it's complete, the window just disappears.

UPDATE: To remove this functionality, Open regedit.exe and navigate to the following location:

HKEY_CLASSES_ROOT\Drive\shell\

Then delete the Defrag folder and close Regedit.

Restore lost drives

If you are not able to locate your drive which was previously there, you can restore that by downloading XP_CD-DVD-Fix.zip and save this file to your hard drive. Navigate to where you saved it and double click the file to extract the contents. Locate the EXE file you extracted and double click it. A confirmation dialog will appear when the script is done. You may need to reboot for the change to take effect.

This utility is only intended for Windows^® XP. You may need Administrator level access to use this utility. If you do not have Administrator level access, the program will say it is finished, but will not have made any changes.
