Hello,
I've clean-installed a Windows 10 Home on a PC which had Windows 7 Home (with OEM key present), but now am unable to activate the Windows 10 with the OEM key available. I read that Microsoft is now allowing the use of existing OEM keys to activate Win 10, and also I've got the Windows 10 10586 (1511) version, which I validated using the "winver" command after installation. The 1511 ISO was downloaded from Microsoft's website, and not tampered with.
Any help on this issue would be most welcome.
Cheers...
