Hi
Thanks for your reply.
From your description, it seems that the expired password is for your local administrator account. If that is the case, you will need to remember the old password and then reset a new one. Once you have accessed Windows, disable the password expiration feature so that your password will not expire in the future.
If you are getting “Your password has expired and must be changed” error. Click on the “OK” button and Windows will allow you to change the password then and there. Then you will have to enter the old password.
Once you are logged in with a new password, now disable the Windows password expiry feature so that it does not occur again. Right-click on “My Computer” or “This PC” and open “Manage”.
It will open the Computer Management window. Here, expand the “Local Users and Groups” menu and open “Users”. Now, right-click on your username and open “Properties”.
Untick the “Password never expires” checkbox and click on the “OK” button. And your password on Windows 10 will not expire in the future.
Wouldn't having the checkbox unchecked cause it to expire???
