SlimCleaner uses community-sourced information to determine what data is safe to purge from a system.Īll of the utilities featured here work in roughly the similar fashion. For reference, 2830 issues were found on our test machine and it would cost $35 for the full version that would supposedly fix them all. That’s just not enough to be useful in the real world.

See, the free edition of PC Booster gives users the ability to fix only 15 issues. COMODO System Utilities wasn’t too far behind at 13.2MB and the free edition of PC Booster came in at a paltry 2.7MB, but it turned out to be severely limited in its usefulness. Both are completely free for personal use, don’t include any useless or bloated software, sport simple interfaces, and weigh in at only 718K (SlimCleaner) and 4MB (CCleaner).Īshampoo WinOptimizer was the largest of the bunch at 16.9MB and had the most complicated interface. SlimCleaner and CCleaner are the no-nonsense members of the group. Piriform CCleaner is best suited to experienced PC users that want to know what they’re cleaning from their systems.
