I've got an XP Home system that I want to upgrade to XP Pro. After I
upgrade the XP Home system to XP Pro can I reinstall the XP Home system on
another Win 98SE PC that I have? The XP Home system is the upgrade
version.
Only if you buy the FULL version of Windows XP Pro. Otherwise, an *upgrade*
version is tied to the prior version that it upgrades. If you start with a
full version of Windows 95 and then use a chain of *upgrade* versions of
Windows 98, Windows ME, Windows NT4, Windows 2000, Windows XP Home, and
finally Windows XP Pro then you still only have ONE license for Windows.
The upgrade version chains back to some FULL version that you possess.
However, that is not how upgrading works because the upgrade version doesn't
require you to insert the FULL version. It just wants the prior version
from which you are upgrading. That still doesn't mean sliding Windows XP
Home to another computer is legal. It is also likely that the Windows XP
Home is an OEM version which means it can never move from whatever was the
qualifying hardware to which that license is attached (which, for most
users, is the computer the OEM version was installed on).
Obviously there is a big difference between what you can do and what you can
legally do. The EULA says, "If the SOFTWARE is an upgrade, any transfer
must also
include all prior versions of the SOFTWARE", and also says, "After
upgrading, you may no longer use the SOFTWARE that formed the basis for your
upgrade eligibility (unless otherwise provided)." An upgrade does NOT give
you another license for the product. You are upgrading the SAME license.
