This is a home computer that has several accounts. The image displayed is Seattle which is not the lock image for any account (including the hidden administrator account). I would like to change this pre-login/sign-out image to something (anything) else. What steps do I need to take to avoid having to look at this stupid image (sorry Microsoft, not all of us are from Seattle nor want any image that looks drawn from crayons)?

If you are referring to Lock screen on the computer, then let us try the following steps by navigating to “Change PC settings” on the computer.

Please follow the steps:
