Lets see if you have a reset in place. You said it was windows 10.
If you are putting in the password ***** it isnt saying you are wrong with hints over and over or microsoft online, there is not a way to move forward from there.
Shut down the windows 10 computer, start it.. When it gets to the windows sign in screen, dont sign in.
Instead, left click the power button at the bottom right.
Then, hold down the shift key on your keyboard, and then click restart.
This should bring you to the blue screen menu.. Choose troubleshooting, advanced, and then choose system restore.
Once system restore loads, choose a restore point that was one day before this problem started and then carry out the system restore.
That should fix the issue, but if you get stuck or this doesnt work then please send a detailed reply and I will assist you further as needed.
Let me know if there is a restore point from before this happen do your pc and results.
