Greeting in short i did the upgrade from windows 8 to 8.1 in store (have a french version)and i extracted the file .esd and a folder C:\windows~T when i try to use the setup from the folder / or even the source they ask me to put the key i already have a EN iso windows 8.1 SL OEM from the store download from torrent but since my pr-installed system is FR windows 8 SL OEM can't upgrade because of cross language problem but the generic keys works fine in that version but my version FR one don't accept any key the only option that i have is to convert my .esd file to iso and try upgrade but i think i won't work because it's must be downloaded and installed by the store not manually think so any one the EN and the FR are extracted from the store so what the difference why the FR doesn't accept generic key
but that no a OEM but it download retail version so i can't use win 8.1 OEM to upgrade my win 8 OEM and i can't use my win 8OEM key for fresh install so i need a retail copy win 8.1 same edition and i can use my win 8 OEM key right??
You can use every version except enterprise, and you don't need generic key if you got OEM-SLP or OEM-NONSLP license.
i begin to hate this version after upgrading from the store to 8.1 SL it's all ok until my windows did some update to find my system inactive and upgraded to pro by itself just someone tell me WTH is going on ???!!
