It all depends on the license for XP Pro you own. If it was supplied by HP,
it is probably an OEM copy, so it could conceivably be used as the base for
an upgrade to Vista Ultimate, but not Vista Home Premium, since that is not
a valid upgrade path for Vista Home Premium.
Valid upgrade paths for Vista:
XP Home->Vista Home Basic
XP Home->Vista Home Premium.
XP Home-> Vista Business.
XP Home-> Vista Ultimate
XP Media Center Edition 2005->Vista Home Premium/Vista Ultimate
All other valid upgrade paths are:
Win2k/XP Pro->Vista Business/Vista Ultimate
Any other path would be a "downgrade", not an upgrade, and must be installed
"clean".
