id like to get rid of all the useless cruft that the operating system and application developers feel should be on my hard drive. id love to see software take out its own garbage for a change rather than force the user to either mindlessly delete things, or trust some other application to do it for you. these days i just treat my c drive as a no mans land that i can nuke at any moment without batting an eyelash. i would have love to live in a world where i didnt have to write a batch file to set up junction points for actual data folders each time i nuked the os from orbit.
that said i dont trust the cleanup utilities any further than i could throw them. the thing that really makes me skeptical is when i go down the os install checklist to the letter, and install everything the way the instructions provided by the manufacturer said to, and everything is working fine and dandy. then have a utility tell me i have over a thousand things wrong with my computer is just plain bogus. i used to be a system builder so im very picky about my os installs being perfect.
obviously you can tell that when a scan utility does this, and especially when there is a pro version that costs money. they are almost always a scam. some of them might be legit, but im not going to try them to find out.
