There are many Windows “Tweakers” out there but not many are freeware or made by a MVP. And this last point is very important when you are putting the stability of your OS in the hands of this type of software. Ultimate Windows Tweaker is Free and was made by Ramesh Kumar, MVP in Windows Desktop Experience.
Ultimate Windows Tweaker is a freeware Tweak UI Utility for tweaking and optimizing Windows Vista, 32-bit & 64-bit. It can simply be downloaded and used as a portable application to customize your Windows Vista to meet your requirements. With judicious tweaking, It can make your system faster, more stable, and more secure with just a few mouse clicks. The tweaker detects whether you have IE 7 or IE 8 installed and accordingly offers you the relevant tweaks only. This Tweaker was released at the Microsoft South Asia MVP Meet 2008.
