A better question is why is MS Cleanmgr so slow??????

[DjLizard]

CCleaner's so fast because it does almost everything in Win32 API, and file deletion is pretty quick in general (in Windows, files are not zero-filled or actually deleted, but simply *marked for deletion* via the filesystem) -- MS Cleanup Wizard is slow because it does additional things such as checking for compressible files, and compressing them, etc.

I wish CCleaner could overwrite things.

This takes ages, but it shreds ALL free space:

After files are deleted by CCleaner, shred the free space using Sysinternals' command-line utility SDelete.

Extract sdelete.exe to C:\windows\system32 (if in XP) or C:\windows\command (if in 98) and start a command prompt session (Start, Run, CMD, if in XP, or Start, Run, COMMAND, if in 98) then type SDELETE -z

Please don't link straight to the exe file. A better link would be to the Sdelete product page (eg. SDelete).

I use Eraser for overwriting free space. It does take some time.
