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.
