How to Uninstall the Vista SP1

Information

You can remove SP1 by using either Programs and Features or the command line. Note, however, that you cannot uninstall SP1 offline using any method. In addition, it is not possible to uninstall the permanent prerequisite updates (KB937287, KB935509, and KB938371). However, you can uninstall KB936330 and KB937954. You also cannot uninstall the service pack and other updates that were installed using an integrated installation. For more information, see: Microsoft Help and Support: KB948537

Nice, information and command line. This is the 2nd time i have tried sp1, and both times it seems to mess with performance. If it takes as long to uninstall sp1 as it did to install it, I think it would be way quicker to just re-install.

LOL, I hear you ggbib. If you do not have any data on the hard drive that you care about, then yes it will be faster for you to just do another clean install.
