Good program. I've only been using it for a couple of days, so I haven't built up much of a "add this/change that" list. After reading most of the prior postings, I would agree that one significant change to CCleaner would be the ability to selectively delete items found after running the Cleaner module (Analyze mood). This option does exist in the Issues module, though such an option should when dealing with the Registry. Also, a "take along" version would be great as well. Like Narok90 stated, many of my clients are weary of programs installed on their systems, when I attempting to fix them. But there concerns are based on someone else using them improperly after I've done my job and departed. Narok90, what other flash drive programs do you use?
