What's the difference between Windows XP Home and the
Windows XP Home Upgrade?
When you say just "Windows XP Home," I assume you mean the full retail version.
There are actually three, not two, versions available: Full, Upgrade, and OEM. They all (assuming that the OEM version is a complete generic one, not a customized one for a specific computer brand) contain the identical software. The differences between them are as follows.
1. The Full version can do a clean installation or an upgrade of a previous qualifying version.
2. The Upgrade version can also do a clean installation or an upgrade of a previous qualifying version. However, it has an additional restriction, requiring proof of ownership of that previous qualifying version. You provide that proof in one of two ways: having it installed on the hard disk (normally because you're upgrading over the top of it), or (when doing a clean installation) by inserting the previous qualifying version's CD when prompted to do so.
3. The OEM version has the most restrictions:
a. Its license ties it permanently to the first computer
it's installed on. It can never be moved to another
computer, sold, or given away.
b. It can only do a clean installation, not an upgrade.
c. Microsoft provides no support for OEM versions. You
have to get any needed support from your OEM, and
that may range anywhere between good and non-existent.
