It would be nice to see an option that allows you to set CCleaner's CPU priority (even if it's just Normal, BelowNormal and Low). I run CCleaner instead of emptying the recycle bin, just to get all the other things that CCleaner cleans as well. I'm also a fan of the 7 pass deletion, and it sucks up the whole cpu for a few minutes sometimes, depending on how many files are in the recycle bin. Just a thought...
Welcome to the forums!
No offense but that sounds like a total complete waste of time especially since CCleaner only takes a few seconds to complete everything it does. To each their own though.
Update to beta 2 the old VB ver 1.xx version had really bad secure deletion performance.
