WinOptimizer 14 Review

PROS / You can choose between a quick or full scan depending on how much help your computer needs.

CONS / You can't erase or manage your hard drive partitions.

 VERDICT / For solving problems or keeping your system working for years to come, WinOptimizer can do most of the work for you.

Ashampoo's WinOptimizer is a PC system utility suite of performance-optimizing tools for your computer. The app is designed to help you back up and restore your computer, recover accidentally deleted files, remove junk files, shred files permanently and more. However, the best PC system utility software is only as good as its ability to improve your computer's performance, and the improvement made by WinOptimizer in our tests was minimal. Several facets of performance experienced slower performance.

As with each PC cleaner software application on our lineup, we tested WinOptimizer's tools on our slow test PC. Then we used PCMark 8 to test the word and data processing, graphics processing, web browsing speed and video chat quality. We used BootRacer to measure the boot-up speed before and after optimization. We also evaluated the ease of use and recorded the scans for consistency. We ran multiple rounds of tests so that our data was an average result.

Overall, WinOptimizer improved our computer by 6 percent, which was below average and not noticeable unless you have benchmarking software. Of course, even the highest-performing product in our review wasn't noticeable on a practical level.

That's the reality of PC system utility software: If your computer is slow, even the best PC system utility software isn't going to magically fix it. However, it's worth noting that WinOptimizer actually decreased the graphics processing and web browsing speeds of our test PC, though not by much.

This PC optimization software only increased our boot-up speed by 5.5 percent. This is more noticeable than the overall improvement, but not by much. For example, 5.5 percent of a minute is just over three seconds – noticeable, but only if you're really paying close attention.

WinOptimizer received a 77.5 percent consistency score, which was also below average. PC system utility software is notorious for exaggerating the number of issues it finds, because these apps want you to feel like you need the software.

To determine this score, we scanned our computer multiple times in each of the three rounds of testing we conducted. After fixing all of the errors it recognized, we scanned the computer again. Logically, if it fixed all the issues it previously recognized, then it shouldn't recognize any more issues immediately after fixing them. But that is exactly what happened with WinOptimizer: It would detect new issues when we re-scanned the computer. Still, it wasn't the least-inconsistent app.

Every PC maintenance software in our review is designed to be easy to use, but WinOptimizer proved to be one of the easier to use, receiving a B+ for ease of use. The interface is clean and easy to follow. It automates most of the optimization, though you have the option to dive deeper with several convenience and optimization tools that are available. So while WinOptimizer wasn't the best-performing app, it doesn't lack for features.


WinOptimizer 14 failed to impress us with its performance in our tests. It only produced an overall performance improvement of 6 percent, despite slowing our test computer's graphics processing and web browsing speeds. If you have very little PC experience or training, use the one-click optimizer, and this software will run all the reports and fix all the problems for you. On a positive note, it's among the easiest PC cleaner apps for a novice user.
