vLite

vLite is an application for Windows Vista that lets you deactivate certain options in the operating system you consider unnecessary and slow down your computer. If Vista isn't performing as fast as you want, vLite can help you get rid of what's weighing it down. vLite can also be used to create bootable ISO images for the operating system, containing all your previous settings. Thanks to vLite, installing Windows Vista is a whole lot easier. That's because you're only installing the features you actually want and need. vLite is a version for Vista of the classic nLite, which offers the same features for other Microsoft operating systems.
