I purchased the upgrade version of Vista Business and would appreciate
verification of what I've found:
When doing the upgrade, it required a pre-existing installation of a valid
O/S, like WinXP SP2. It is not sufficient to input just a license key from
the older valid O/S, so if you ever need to re-install Vista, you have to
reinstall the older O/S first. Ouch.
Is that right or did I miss something?
