"Microsoft has increased both the power and complexity of its popular Windows operating system with the release of Windows Vista. Stardock’s TweakVista™ enhancement application helps you configure Windows Vista to meet your personal needs by improving performance. Unlike other power tools for Windows, TweakVista™ automatically prompts enhancement recommendations, offering easy “one click” updates to otherwise complex configuration changes. TweakVista™ is also safe to use. By utilizing Microsoft’s system-restore technology any changes you make can easily be rolled back. You can freely experiment with different settings without disabling your computer."
Want to get the most out of Vista? Check out Tweak Vista from the master coders at Stardock - they make good stuff, so I'm sure this will be top notch. I'm not sure how much stock I place in the performance enhancements, but the program offers a lot of other options worth checking out.
