As far as I can see nowhere in the procedure you indicate (unless I've
missed it) does it ask for the product key. In this case you are simply
rolling back the upgrade. If, however, you were to disregard the rollback
option and, instead, simply do a clean install, you would be required to
enter an XP product key code which, although you would be able to install XP
gain, as far as I am aware, it you couldn't be able to activate the copy.
If, as you say, XP crashed during this procedure then there isn't a lot
anyone can do, unfortunately. I don't make the rules, Microsoft does.
As for OEM and/or upgrades, personally, I would buy neither. A full retail
copy gives you more scope should you decide to change our PC and then
install Vista on that machine (assuming it didn't already come with the
version of Vista you previously purchased). Buying an OEM does give you some
lee way, but doesn't offer any Microsoft support. Remember OEM copies are
meant for system builders and, as such, the system builder is responsible
for all support, not Microsoft.
