He praises the work Microsoft has done on the installation program, but thinks it still presents problems for those who wish to upgrade. He recommends the free Windows Vista Upgrade Adviser. Then, be sure to pick the best edition for your use." From the article: "Don't bother wiping your hard disk. Just run the in-place upgrade from your previous installation. You'll be given the option to perform either an Upgrade or Custom (advanced) installation. Opt for the Custom install to clean-install Vista, and Windows Vista Setup does something smart: It creates a folder called Windows.old in your root directory that contains your old Documents and Settings, Program Files and Windows folders. (Note that on my test machine, this added step used an additional 7GB of disk storage.)"
