When you install Windows Vista or XP, you're installing vanilla operating system that has been designed to work across a range of different hardware configurations. It's not particularly optimised for your specific machine. You might not even realise that there are a number options within your operating system that are hidden as default. You can access these hidden options by using a tweaking or optimisation tool.
Ashampoo WinOptimizer 4.4 is a tweaking and optimisation tool that will enable you to get the most from your operating system, based on the software and hardware installed on your computer. It goes further though and includes a Registry tweaking tool and a disc defragmentation utility, so you can speed up your PC.
