I've been using Ashampoo's software for years. Especially WinOptimizer is an awesome program. Just tried the new version 11 with gamebooster and all other new innovations. All I can say: It works like a charm and my computer is so much faster. Their products are always excellent. Even pcworld.com says that WinOptimizer is better than CCleaner...look at this review http://www.pcworld.com/article/2142625/winoptimizer-11-review-everything-you-need-to-tune-up-your-pc-under-one-roof.html
