The free version is, as you'd expect, the least feature-packed option. Piriform has corrected the problem in subsequent CCleaner releases. Still, Iolo System Mechanic remains the category's Editors' Choice due to its thorough cleaning tools and unlimited licenses.Įditors' Note: This is PCMag's first CCleaner review since the tune-up utility suffered malware-related issues in 2017. CCleaner is pricier than Windows 10's free, integrated tune-up tools, but it comes in at a lower price than some competing products, offers features that dramatically improved our testbed's boot time, and is easy enough to use that it's worth the investment.

It boasts many system-enhancing features, including a registry repairer and real-time system monitoring, as well as extra features like privacy protection and drive-wiping tools. Piriform's CCleaner Professional Plus is one of many tune-up utilities capable of giving a heavily used PC a new shot at life.

Performance improvement not as large as the competition's in some areas.
