Yep. This issue has been <profanity removed> my system for 2 years. Still never got it updated. Just tried again for the 150th time and now i am locked out of my pc entirely. I used ONLY Microsoft suggested tactics from only Microsoft websites. I am wildly baffled that this is STILL going on. Im even more perplexed that it hasnt been on the news everyday since it started years ago. Im far from a basic user and i cant get it. This is trash. Bad. IF i can even get my system back at all, I am 100 percent putting Linux on this machine. Goodbye absolutely every single thing Microsoft. FOREVER.
I had just previously posted this: "This happened to me for the first time and I solved it without being a Microsoft guru. The answer is a little counterintuitive.
When the login window appears click the "Did you forget your PIN?" link. It'll make you log in to your Microsoft account and send a code to your cell phone to verify it's you. You can then reset the PIN. I just used the old PIN. Once reset, the login window will reappear, and I was able to get in using the newly reset old PIN!"
