The Username or password in incorrect. Try Again

The installation of Windows 10 Pro 64 bit on my PC is only a couple of months old and was going fine until I decided I didn't need a Login password and unticked the relevant box in User Accounts.

Now when I start the computer I get the following message on the startup screen 'The username or password is incorrect. Try Again.

I then enter my user name and password but these are not accepted after trying on numerous occasions.

The only way I can start Windows is by inserting my Microsoft Login details.

Could someone please advise how to rectify the problem.

Thanks Brink for your response.

I followed your advice and ticked the box Users must enter............. and set up a new pin number.

When I restarted the computer I entered the new pin and everything was OK. Again I went to netplwiz and unchecked the relevant box and when I restarted the computer I again got the message 'The user name or password is incorrect!

Somewhat odd isn't it?

I think the problem has been resolved.

After unticking the box in netplwiz there is a request to enter a username and password.

I was entering the correct username but I was entering my pin number instead of my Microsoft password.

When I switched to the Microsoft password the computer now starts without any error messages.

Thanks Brink for your help.
