Fix 3: Unlock Microsoft account with Microsoft service
When you attempt to sign in Windows 10 with an incorrect password, you will get a message that contains the link allowing you to reset password. Note down the link.

On any one computer or phone device, open the link in the browser. Then follow its guide to recover your Microsoft account.


Enter your Microsoft Account information, which can be either the primary email address or phone number, followed by the captcha challenge to prove that you're a not a robot.

Pick how you want to receive the security code: email or text message. In either case, you'll need to provide part of the alternative email address or phone number associated with your account.
Click Send code and enter the security code you have received.

Enter your new password (must be 8-characters in length on more). You'll get a message that letting you know that your account has been recovered. Click Next to complete the task.

Go back to your computer and try to sign in again.

Note: To be able to sign in to your account your computer must be connected to the internet. If everything worked as expected, you'll once again be back in your account.

I hope this helps in gettting your account unlocked.
