Disk Cleanup

I've been using the CCleaner for 10 years so have become accustomed to it's instant cleanup, taking about 2-3 minutes to do both Disk and Registry if done monthly.

The other day I tried Disk Cleanup on a friend's computer since I didn't have my programs stick and it was too locked up to download CCLeaner right away. Was appalled at what a slow, clunky, unresponsive app it is to this day. Haven't they learned anything from the state-of-the-art cleaners?

I recommend CCleaner and Auslogics DIsk and REgistry defraggers instead of MS's "legacy" cleaner/defragger turtlethings.

Scannow completed without any errors.

But I discovered that my problem was related to my use of "Classic Start Menu". Thus the location of Disk Cleanup.exe was not "%windir%\system32\cleanmgr.exe" but rather "C:\ProgramData\Microsoft\Windows\Start Menu". I don't know what the difference is between Disk Cleanup.exe and cleanmgr.exe, but the former does not execute. Disk Cleanup.exe is now temporarily residing on my desktop until one of you is able to tell me where it should be moved to.

Since it doesn't execute, why would I want it on my taskbar?

Yes. I can move it there. I'm still wondering since it doesn't execute, what purpose does it serve?
