Not talking about the defragment,just the disc clean up.

iv used CC Cleaner and tried various registry cleaners, but they only scan the computer, tell me how many errors i have and then dont clean them! they want money of course…so annoying lol help

That will scan my computer and download the drivers that I need.

I have a dell computer with a 3 years warranty. if i open it up, then i void the warranty. How can I clean out the dust, if I can’t open it up?
