I recently upgraded my OS from Windows 8.1 professional to version 10 pro. I had reserved my v10 copy months ago but decided to upgrade a couple days after the official release using the Media Creation Tool since I hadn't received it on my laptop yet. After upgrading I logged in to my Microsoft Live account to activate Cortana. I then decided I wanted to login using a PIN rather than having to key-in my full password every time.
The problem is that I cannot create a PIN at all, period. Every time I go into "Sign-in options" under settings, and whether I am using my Microsoft Live login account or a local account, I am prompted to reenter my password. After reentering my password I get a popup titled "Set up a PIN" [see attached image]. Just below a brief description it says, "Just a moment", with a small spinning load circle next to it. And that is where it sits indefinitely. While the "OK" button at the bottom of the popup is clickable, it does absolutely nothing. Not clicking "OK" does nothing either. I have literally let it sit there loading all night and it never actually loads anything beyond this popup and the "Just a moment" load screen. The only option is to cancel.
I have rebooted the computer many times, tried different accounts, changed my full password, tried the official microsoftaccounts.diagcab and WindowsUpdateDiagnostic.diagcab tools for help, but to no avail. I have even tried reinstalling Windows 10, but this problem persists; I cannot create a PIN to use for my login.
Any others out there with this problem on the newly upgraded Windows 10? Windows 8.x solutions do not work. Any updates or ways to fix this?
