I can buy Vista Ultimate OEM legal copy dvd. I am using RC1 now. can I do
and
upgrade or do I have to do a reinstall. Thanks
An OEM copy of Vista cannot do an upgrade. You can upgrade RC1 from a full
retail version of ultimate. You cannot use an upgrade version because RC1
is not a qualifying product.
If you use the OEM version use Windows Easy Transfer (WET) to transfer data
and settings to a USB drive or CD/DVD, then install Vista, reinstall apps,
and use WET to bring back the data and settings.
