Just get Win 10 free upgrade offered even though I don't even have my Windows 8.1 activated. Anyone knows what happens if I upgrade?
it will upgrade and not be activated just like your 8.1 is. Only way to get 10 activated properly is by having the original OS activated prior to upgrading.
Or, use your Win7/8 product key for activation in build 1511, clean install...I think I would do that before I'd go the "reinstall-old-OS then upgrade-to-Win10" route.
Build 10586 can take Win7/8/8.1 keys directly like Wun10 keys but not all, only specific (non-global) keys (retail, coa, bios dm)
Ah something new to play with then. Interesting, I guess the win10 adoption needed to be upped lol Thanks
