WinOptimizer tracked each process and marked its completion with a green check mark the whole process took less than a minute. We saw no red flags in WinOptimizer's selections, so we clicked Start Optimization. We reviewed each recommendation, which WinOptimizer explains in detail under each category, with the opportunity to deselect any item from the cleaning and optimizing process.

WinOptimizer made 15 recommendations over five categories, including three unnecessary startup entries in the StartUp-Tuner, seven superfluous system settings in the Tweaking tool, and 97MB of junk files flagged by the Drive Cleaner (a lot of space, even with today's drives).

We started WinOptimizer with a Full Scan, which completed quickly. Ashampoo's WinOptimizer Free is one of the best such tools we've tried. A really good tool would also help you tune and tweak your system by disabling unnecessary features and settings. A decent system cleaner and optimizer can make a big difference in your PC's performance by tossing out junk files and tightening the Registry.
