Potentially pricey Lacks unlimited licenses If there's one thing we've all experienced as Windows PC users, it's the inevitable degradation of our computers. After all, PCs get bogged down with junk files, registry issues, fragmented hard drives, and other computer-related ills. Fortunately, AVG TuneUp can deal with those issues, and give your PC a jolt of new life. Although the application duplicates some of Windows 10's basic, built-in tune-up tools, it's worth a purchase if you want a simple way to improve your PC's performance. Prices and Licenses AVG TuneUp is available in free and premium varieties. Unlike many other tune-up utilities, AVG TuneUp's free tier lets you clean up a PC. There is, however, a 30-day limit before the app asks you to shell out a pricey $69.99-per-year subscription. Fortunately, AVG runs many TuneUp discounts, so you can download the app for, say, $29.99 (its price at the time of this writing). For comparison, Ashampoo WinOptimizer costs $49.99 (as a one-time purchase) and Iolo System Mechanic costs $49.95 (as an annual purchase).
