I have been using Windows 10 without any problem, until I did a system restore. When the computer rebooted, it would not recognize my password, even though it was correct. I have changed my Microsoft Account password, but that didn't work. I have the local account and the Microsoft account on the computer. Neither one accepts the password. I am using Windows 10 on two other computers without any problem. Any suggestions on getting the computer to recognize the password? I can't get past the login window to access anything.
