No a full version is not an upgrade, as you do not need to have either another operating system installed first, or a blank hard drive and the older operating systems CD and licence key handy. That is why upgrades are cheaper, as you are not buying the licence number etc a fresh, even though the upgrade can be installed onto a empty hard drive. A full version will over write the older version of Windows, or ask you if you want to dual boot it, but you still need a full Licence number for that new OS. Hope that explains it for you.

That is, if I can find an UPGRADE version, as opposed to the full version I already have. Doesn't the full version act as an upgrade version as well?
