"If there's ever been an operating system that could use some slimming down, it's Windows Vista. Enter vLite, a donation-supported software tool by Dino Nuhagic that lets you create a Vista installation DVD that leaves out drivers and programs you don't want, installs Vista so that it begins with settings and options that you do want, and lets you install Vista without responding to any prompts. It does this by automating procedures that are thoroughly documented by Microsoft , but which normally require hours of work modifying installation files by hand. I used vLite to create a slimmed-down automated Vista installation DVD that let me get a new system up and running faster and more efficiently than the DVD that I bought from Microsoft. As long as you make these changes only to your own copy of Vista, and you don't distribute the resulting DVD, this seems to be a perfectly legal way of automating changes that Microsoft supports anyway."
