I can`t get my disk cleanup to work. i ran spybot and found no errors, but still nothing and my pc is running very slow..Any ideas on what is going on. I also tried setting back to an earlier date with no help..

Noticed this problem with a couple of computers I have worked on...have you installed any utilities lately, especially proprietary disk defrag programs?

SYMPTOMS: When you try to run the Windows XP Disk Cleanup tool, it may stop responding. CAUSE: This problem occurs because you have a corrupted temporary file on the computer. RESOLUTION: To resolve this problem, delete all the files in the current user's Temp folder, and then delete all the user's temporary Internet files. To do this, follow these steps: Click Start, click Run, type: %temp%, and then click OK to open the Temp folder. In the Temp folder, on the Edit menu, click Select All, press the DELETE key, and then click Yes to confirm that you want to send all the items to the Recycle Bin. Click Start, click Control Panel, and then double-click Internet Options. On the General tab, click Delete Files. Click to select the Delete all offline content check box, and then click OK. Click Start, and then click My Computer. Right-click the drive that you want to clean, and then click Properties. Click Disk Cleanup to run the Disk Cleanup tool again.

I have deleted all of the programs that i think might be using it, even my display and i still can`t get rid of it,,,any ideas,, HELP

bevcaron, Regarding perflib_perfdata_708, I also have this locked temoporary file in my temp directory. Take a look at the link below to read what others wrote about the how and why this file was generated (as an fyi, there's really nothing to worry about. btw it's a long thread http://www.experts-exchange.com/Security/Win_Security/Q_20417096.html
