Customer Reviews

4.5 / 5
Saved me

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.

Gives me an edge

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.
