I noticed the C drive on my server was down to 10 GB of free space when earlier this week it was at 20 GB.
I ran Disk Cleanup, checked every item (which totaled about 20 GB to delete). I clicked Ok.
A window appears: "The Disk Cleanup utility is cleaning up unnecessary files on your machine."
The window went away and I rebooted the Server.
After reboot, the amount of free space is still 1 GB, when it should be at least 30 GB.
Even my c:\Windows\Winsxs folder is 12 GB in size with the oldest file dating back to 7/13/2009.
Does it take time (after the Disk Cleanup) window disappears, to actually delete all the files discovered by Disk Cleanup?
Does Disk Cleanup really delete the files, or just moves them to the recycle bin?
Note: The version of "cleanmgr.exe" and "cleanmgr.dll" running on the Server is 6.1.7600.16385 dated 7/13/2009.
Am I overlooking something?
