The username and password of Win10 are incorrect.
Many of my friends have encountered the problem that the username and password are incorrect when Win10 is turned on. I don't know what's going on. According to the user's description, after the user name and password are incorrect when Win10 is turned on, click "OK".

In fact, the cause of the above problem may be that you have changed the computer name when you set Windows 10 To Enable Automatic Logon. Select any account on the welcome page and enter your password (or login name and password ).
After successfully entering the Windows system, press "Win + R ".
Enter netplwiz (or control userpasswords2) in the window ).
Select "to use this computer, you must enter the user name and password (E)" and click "Apply ".
Disable it, that is, deselect the check box. Then the system will resume normal automatic login.
