It s frustrating when your PC s performance slows to a crawl, but that doesn t mean it s time to purchase a new computer. A tune-up utility, such as Iolo System Mechanic, can whip your machine back into shape with just a few clicks. But is the app worth its $49.95-per-year subscription price? Maybe. Iolo System Mechanic improves your PC s performance by defragging the hard drive, deleting junk files, tweaking CPU and RAM usage in real time, and executing other computer-enhancing tasks. Plus, the latest version improves several longtime features, while adding a revamped, attractive interface. So why the tepid recommendation? You don t necessarily need Iolo System Mechanic to get most of these benefits if you re the intrepid type who doesn t mind diving deep into Windows 10 to find similarly effective tools.
