I have been using Window Washer to cleanup my system, but after noting that a number of you use CCleaner, I decided to d/l it and give it a go. As a test (of sorts), I first cleaned my system using WinXP's Disk Cleanup, followed by Window Washer, and lastly CCleaner. After WinXP's cleaner did it's job, Window Washer found and cleaned another 9MB of files that remained. After WW did its job I ran CCleaner and it found 122 more files (about 33MB) that it would have deleted had I proceeded, but I was afraid to 'pull the trigger'! Some of you (pvsurfer, most recently) have mentioned that CCleaner is extremely aggressive (which my test confirms), so I'm wondering how many of you consider it safe to blindly allow it to perform its cleaning actions?
