I think UEFI is pushing the win8.1 you've already done the free upgrade there is no need to "force activation". I forced restart after waiting for 20-30 minute it gets reverted back to WIN7 back and my Windows 7 Genuine activation will also be terminated.

I have tried updgrading to WIN10, it goes till the first restart after installation and get stuck there at WIN 10 Boot Logo. I am currently on a Windows 7 Acer OEM, ultimate 64 Bit, pre activated version.
