4 Vista Manager
This Vista tweaker from Yamicsoft may be the most powerful one of the bunch. Vista Manager serves as an umbrella, uniting many utilities in a single interface.
Whether you want to speed up your system, repair it, optimise Internet Explorer, enhance security or adjust the way your network works, you’ll find something here that can do the job. Vista Manager also lets you customise the Desktop, Start menu, Taskbar and your icons. A Registry defragmenter and cleaner is equally useful.
