Customer Reviews
4.5 / 5

I was on the verge of buying a new PC because it was running so slow. I used to have to wait about 5 minutes for my PC to boot up and another minute in between web pages! I couldn't run more than two programs at a time without it freezing. I saw STOPzilla Optimizer and tried it out. I have to say STOPzilla Optimizer will always be one of the first programs I will ever install on my computers in the future. It saved me from having to buy a new computer—this one runs like new.

As a PC gamer, speed means a lot to me. Manual optimization can only do so much, and messing with the registry is too risky. I love STOPzilla Optimizer because it cleans out my computer regularly, updates my drivers and keeps my frame rates high, giving me an edge on the competition.

I've been using STOPzilla since the dragon when I saw STOPzilla Optimizer. I didn't understand that your computer "ages" and becomes slower with time. STOPzilla Optimizer did everything I never knew was possible for my PC – it runs like new and I have a lot more space now that all of the junk files are gone. I can't believe the difference.

I was quickly able to find and fix registry errors, free up hard disk space and easily perform a quick performance check. It was all so simple.
