After you finish following these directions Disk Defragmenter should be
available to do its magic.2.
Re-register the defragmenters snap-in files
It is possible
you install a third-party
defragmenter like Diskeeper, then on
uninstalling, it does not restore the built-in one correctly. Open
Command Prompt (good ol' DOS) by clicking Start -> All Programs -> Accessories -> Command Prompt.
At the command prompt type,
then register the defrag components, by typing:regsvr32 dfrgsnap.dll
this stage, you may find the disc defragmenter works. If not, there is
one more step you can do.

browse to your windows\inf

find a file called dfrg.inf

and adequately defragment it. Defrag
uses this space as a

free space on a volume, delete unneeded files or move them to another

Install and run third-party disk defragmenting software.8. If all of the above possible solutions

just because of disk defragmenter).
