Pros / This app has comprehensive convenience features and advanced tools.

Cons / The overall improvement it produced was among the lowest in our tests.

 Verdict / While Ashampoo's WinOptimizer has comprehensive tools and features, the overall improvement and the boot-up improvement wasn't impressive.

Developed by Ashampoo, WinOptimizer is a suite of PC repair software with a load of maintenance and monitoring tools. With this app, you can back up and restore your computer, recover lost files, remove junk files, and permanently delete files. However, the most important consideration for any system repair app is how well it improves your computer's performance. And unfortunately, WinOptimizer's improvements to both the overall performance and boot-up speed were among the lowest in our review.

As with each PC repair software application in our review, we tested WinOptimizer by using it to diagnose, repair and optimize our slow test computer. We used PCMark 8 to benchmark our test computer's performance, both before and after testing, to see whether various facets of the PC's performance improved.

The benchmarking tests evaluated word and data processing, graphics processing, web browsing speed and video chat quality. We used BootRacer to precisely record the boot-up speed before and after optimization. Finally, we evaluated the ease of use and recorded the diagnostic scans for consistency.

Our tests revealed that WinOptimizer only improved our test computer by an average of 6 percent, which was the second lowest overall result. That said, even the best-performing app in our review, which improved performance 12.5 percent, didn't improve performance enough for it to be noticeable without benchmarking software.

Unfortunately, minimal improvements are a reality of system repair software: If your computer is slow, it's unlikely to change much after using this software. In fact, it can hurt performance. For example, WinOptimizer actually decreased the graphics processing and web browsing speeds of our test PC, though not by much.

Another disappointment is the 5.5 percent improvement to the boot-up speed. If your computer took one minute to start up, this improvement would result in a bootup that was a little over three seconds faster. When you consider that the best system repair software in our review routinely improved boot-up speeds by between 25 and 32 percent, this is a significant disappointment.

The diagnostic consistency received a 77.5 percent consistency score, which was also below average. This score was determined after almost 30 rounds of scanning our test PC for errors, fixing the errors and rescanning. For a PC system repair app to be perfectly consistent, it shouldn't recognize issues or errors on the second scan. Unfortunately, WinOptimizer wasn't consistent about one-fourth of the time. Still, there are other disk repair apps that have much lower consistency scores.

Each app in our review is meant to be easy to use for a novice user, and WinOptimizer was definitely one of the easiest. We gave it a B+ for ease of use. The interface is uncluttered and easy to follow. There are a few unnecessary steps, and most of the optimization is automated.

Most system repair software apps come with a bevy of tools, but few can match the comprehensiveness of WinOptimizer. The app has every monitoring tool available to ensure that your hard drive and RAM are running effectively. It also has nearly every advanced tool we deemed important enough to consider. The only advanced tool it lacks is a solid-state drive optimizer.

Ashampoo's WinOptimizer is a system repair software program with an impressive list of convenience features and advanced tools. However, it failed to impress with its performance in our tests. It only improved our test computer by an average of 6 percent and even slowed the graphics processing web-browsing performance. In addition, the diagnostic consistency was below average with a 77.5 percent score. On a positive note, it's among the easiest PC cleaner apps for a novice user.
