CCleaner is great, but I have found that a lot of times people end up with tons of trash on left behind user directories that either got corrupted, or they just don't log into because it is C:\Documents and Settings\LocalService, or the NetworkService folders.
Problem is, that sometimes the Local Settings folder that contains temp & temporary internet files folder can get full of internet trash. Thousands of items.
Like, Content.IE folders.
Can you add the option for CCleaner to scan for Content.IE folders to empty under Documents and Settings folder/*.* users?
That way, hundreds, or even thousands of megs of trash can be erased that people did not even know was there. And it would be 100% safe & foolproof
