I have about 8 people that have accounts on our pc. I set it up to clean temp files for each user but it only cleans the files of the person that is logged on. I am using windows 7 and windows xp use to clean all users files.
This is a feature that is requested frequently, but left out because other people may not wish their files to be tampered with. I believe there is a batch script somewhere on the forums that allows you to do it, however.
Without wishing to sound like a salesperson for Piriform, the Pro version has the ability to clean all profiles, or just the ones you choose to clean.

Whether it will ever be part of the free version I have no idea.
