when you try to run windows defrag, or
other times, the defrag window will show
up, but the analyze and defragment
buttons will do nothing.
Solution
The solution is actually quite simple. You need to re-register the defragmenters snap-in files,
and the basic registry entries.
l First open up a Command Prompt, this can be found at:
Start -> All Programs -> Accessories -> Command Prompt
l Change into your windows\system32 directory. Your windows directory will be either
windows or winnt. Type:
cd \windows\system32
l Register the defrag components, by typing:
regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll
