Start with a symptom
WinOptimizer is Ashampoo’s Windows maintenance product. The older ZonaSoft URL refers to the 2015 edition. To evaluate a current edition, start with the problem you need to solve rather than treating a large scan result as proof that every suggested change is useful.
Keep changes reversible
Read the description of each selected action. Retain backups of important files and note the settings you change. If you are troubleshooting a slowdown, change one relevant option at a time and repeat the same task afterwards. A maintenance application cannot replace hardware that is insufficient for a workload.
