Hello, I just bought a full OEM Product Key for Windows 8 Pro. My question is, if I upgrade my current Windows 7 Ultimate installation (OEM licensed as well) to Windows 8 Pro, then can I activate the upgraded installation of Windows 8 Pro using the full OEM license (even though it is an upgraded install, not a fresh one)? Please answer my question, and do not ask me why did I bought a full key for an upgrade. (I did it because it was cheaper than the upgrade at my source) Thanks!
Still did not understand... will my Windows 8 Pro activate with a FPP or OEM or whatever it is key, even if it was upgraded from Windows 7 (with installation started from Windows 7, chose Upgrade to keep files, folders, programs, settings, apps etc) ???
Figured it out: when I inserted the Windows 8 Pro DVD, it asked me to type in the 25-character key. It accepted it and then asked whether I would like to do an upgrade installation or a clean one. Then, it activated Windows with no problem and also kept my old Windows 7 key valid too. It made my day. I purchased it from a third-party in Romania for RON 50 (aprox. $ 15). So happy
Sure that upgrade is cheaper! What I posted above is an OEM Version for which you couldn't buy an Upgrade Version! Upgrades are from MS only!
For Windows 8, System Builder is, for individuals, essentially the new Retail now (though the key is OEM:NSLP). The upgrades from MS are true RETAIL keys, so are the WMC ones.
