After using Windows Washer for over 4 months, I wanted to find something that cleans even deeper, and also cleans the computer from back up or system files I tried using Windows Washer in conjunction with jv16 power tools, but jv would not clean up the "bak" files, on demand, so I gave up on that. I have been using "System Cleaner" (www.allerasoft.com ) and Evidence Washer (www.evidence-washer.com ) which I think is working very well, actually. I am also using Registry First Aid. Evidence Washer seems to REALLY clean up WIndows down to everything. Here is a screenshot; Has anyone else used these? Is there anything better?
