I'm using Microsoft Windows XP Professional Version 2002 Service Pack 3. Starting with the last version and continuing through this version, when I run the cleaner, it freezes at 27%. I noticed that's when it's emptying the recycling bin. If I disable the recycling bin portion of ccleaner, it will run fine. Has this already been reported?
Can you empty the Recycle Bin using the Windows 'Empty Recycle Bin' command?
By any chance do you have an item in the Recycle Bin that was from a now unattached device?
Update your CCleaner version
And, does your Recycle Bin have any sort of protection?
