In addition to older versions of Windows®, the new Ashampoo WinOptimizer 4 is fully compatible with Windows Vista™ in both the 32 and 64 bit versions. This means that you can start maintaining your slick new Vista system right away - it won't even have a chance to get clogged down with new garbage!

But that's not all: Once again, Ashampoo has managed to produce a radically better and more useful program - without compromising their famous ease of use. In addition to Vista compatibility, WinOptimizer 4 also comes with three new modules, a brand-new hard disk defragmenter, a huge number of new system tweaking options and many other improvements and enhancements.
New Modules and Tweaking Tools:
The new version includes three new modules and a completely new Vista-compatible version of the disk defragmenter. In addition to this a very large number of new options has been added to the popular Tweaking Tools module - you can now adjust well over 450 Windows® system settings, and each setting is clearly explained so that you always know what you are doing.

System Benchmark
The System Benchmark module tests the processor (integer and floating point) and memory performance of your system and compares the aggregate result with the performance of reference systems. Check out how your computer stacks up in today's market!
