A Croatian college student has produced a cool little app. that allows users to slipstream SP1 into a new Vista installation. vLite was first created as a way to lessen Windows Vista's footprint upon installation, allowing users to shrink the OS down so far that it takes up only 1.4GB hard drive space after setup. The newest version of vLite, the 1.1.6 Beta, allows for the use of a "Service Pack Slipstream" - which updates the files from an original Vista install disc with SP1, then creates an .iso that can be burned to a DVD that would then be used to install the most up-to-date Vista possible. vLite also allows users a number of ways to customize their Vista installation, including - adding or removing components of the OS, which language packs are installed, and which drivers are installed. For more info on this neat program, you can visit vLite's website and poke around a little.
