Quite a while ago I've learned that there's a folder in %appdata% that stores very, very un-necessary (temporary) files. They're files that get used by browsers, mostly. Such as cookies, background programs, debugs/bugs, random text files, etc. These usually take up disk usage and your memory. Even though I've got a medium/high-end pc, this did help speeding up my pc a bit. Location: appdata\local\temp Shortcut: %temp% Delete everything in this folder, CTRL+A delete. Restarting is recommended Do this regularly, for some reason after a week I have over 2000 files in the folder
