I can use the upgrade version on its own by upgrading itself, but I can't upgrade my current Vista install.
Meaning, I'll be able to use it, it'll just take a little longer to install than if I had a proper Windows 7 Ultimate upgrade.
Are you guys sure that this is going to work in Windows 7? That seems like a pretty huge mistake on their part to allow an upgrade to be used on an unlicensed OS.
