Vista HP -> Win 7 HP (no key) -> Win 7 Pro (valid key)
I want to upgrade my Dad's pc currently running Vista 32 bit home premium, fully legal oem copy with his HP. We have a never used fully legal Windows 7 Professional PID. My question is, how do we upgrade from Vista HP to Win 7 Pro?
Can I upgrade first to Win7 HP, without enter a PID, then do an anytime upgrade right away using our legit Win7 Pro PID?
Many thanks!
ps: would really like to do a clean install of Win7 Pro x64 but he wants to try an upgrade first, and I myself am curious if the above vista hp -> win7 hp -> win7 pro scenario would work anyway.
