Tried to install Anniversary Update but it fails by error 0xC1990. Please help me?

[Windows Central Question]

After the second boot on the updating screen, the one with the spinning thing. When it gets to 83%, my screen just freezes out of nowhere. I tried switching off and back on again but it reverts back to my previous version of Win10. I tried getting Microsoft Support to help but their service wasn't all that great and I wasn't too happy with them. So I'm calling on you guys to help me out.
