You guys are playing with fire. There ain't no unactivated build worldwide and you seek one. I delete the file and made a second installation of 10166. Wish to remind you that this is the one under test.
I'm on 176 and it's 100% fine. For some reason MS compiled their RTM candidates with KMS V6 (from 8) rather then V7 (will be in Final). People already figured out how to emulate V6 awhile ago, thus why this is activateable.

Reason it was unactivated was because it was not an Insider build leak, but what was gonna be RTM.

That said, duel boot this because 100% chance it's not gonna update to anything on 29th.
