Best Free PC Cleaner Utilities

For those times when your computer is starting to feel slow but not enough to necessitate a hardware update, free PC optimizers can provide a modest but noticeable performance increase.

There are a lot of free PC cleaners out there that claim to make your computer run quicker, but not all of them live up to expectations. That's why we've put all of the most popular alternatives to the test and compiled a list of the ones we think would give your PC a considerable speed boost while avoiding any frills or obtrusive adverts.
