Hi, David.

"OEM" and "upgrades" are mutually-exclusive terms. An OEM version is, by
definition, to be installed on a factory-fresh machine, so it can't be used
to upgrade from anything.
And, from your later post:
> Will Windows 7 use Vista or XP drivers?
Windows 7 will need new drivers, which may or may not also work with Vista
or WinXP. Remember that Microsoft writes Windows; hardware manufacturers
write the drivers that make their products work with Windows. Microsoft
works closely with major IHVs (Independent Hardware Vendors) and includes
many available drivers in the Windows package, but the drivers are the
hardware maker's responsibility.
