I regularly run Disk Cleanup without problems. All of a sudden when I choose to run Disk Cleanup it just sits there and does nothing at all. It just 'hangs' there reading 'scanning....compress old files' with the blue progress meter line at the beginning ? Does anybody have any ideas what could cause the Disk Cleanup to suddenly quit working ? I've not added or subtracted anything lately at all. I've successfully run both ScanDisk & Disk Defrag without any problems.

Does delete temp internet files still work?

Hey man Click on start/run and type in sfc /scannow. You will need to put in your XP disk to replace the lost files, but that should fix your problem. Good luck, and post back if it don't work.

Locate, and then click the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches On the File menu, click Export, and then click Desktop, type VolumeCaches in the File name box, and then click Save.
