Reinstall Defrag in windows XP

[Crash1hd]

As the subject says How do you reinstall the defrag utility in windows xp its not in the ad/remove programs?? or how to reinstall all the service tools?

Re-install XP. You can do what is called an Upgrade install and install it over itself to keep from loosing your settings.

Actually, you can do it without re-installing windows. If you ever look at the about box for defragmenter, its licensed from Executive Software who makes Diskeeper, and the lite version comes with windows. You could buy the full version, i don't believe its that much, and you get lots of good features like boot-time defragmentation and stuff.

Just thought I'd point that out.

You could first try to re-register the built-in defragmenter snap-in files first, and the basic registry entries.
First open up a Command Prompt, this can be found at:
Start -> All Programs -> Accessories -> Command Prompt
Change into your windows\system32 directory. Your windows directory will be either windows or winnt. Type:
cd \windows\system32
Register the defrag components, by typing:
regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll
At this stage, you may find the defragmenter works. If not, try there is one more step you can do.

Using Windows Explorer browse to your windows\inf folder.
In there you will find a file called dfrg.inf right click this file, and select Install
And I do agree with OracleGuy, Diskeeper is the number one automatic defragmenter which works invisibly in the background due to the Invisitasking technology in Diskeeper 2009.
