I just want a reasonable explanation why Microsoft made a requirement that Windows Vista Home Basic Upgrade, when installed from XP Pro, has to format the hard drive in order to install. A PC can boot from the Vista Home Basic DVD, then tell you it has to be installed from the desktop. Once at the desktop, it tells you it has to wipe your hard drive. Absurd!
If Win7 has an upgrade, and I can't see why it wouldn't, I really hope it doesn't include such a rediculous requirement.
