Changing login screen background

Hi, I would like to change the picture that is shown after the computer starts or after a user logs out; the one you click on to get to the list of users and log in. I have two accounts on the computer, and in both of them I changed the "Lock Screen" picture to be the stock picture of the piano. When the computer first boots up it shows the piano and I log in, but if I sign out of the account to switch users the picture that is used in the splash screen reverts to the drawing of Seattle. How can I get it to permanently use the piano or for that matter any other picture besides the Seattle one when switching users?

Thanks in advance!

Hello MathGuy, and welcome to Eight Forums.

In Windows 8 there is two "Lock" screens available. One used that is set by a user when they are signed in. The other is the default image used when there are no users signed in.

The only problem is that only Windows 8 Pro, Windows 8 Enterprise, or Windows Server 2012 are able to change the default Lock screen background for when there are no users signed in.

I'm running Pro, but apparently you have to be part of a "domain group" (?) for the process outlined in the tutorial to have any effect. I set the "force specific lock screen image" and "prevent changing lock screen image" settings in gpedit.msc (which also changed the registry values that were mentioned in method two of your tutorial) but that didn't affect anything, which didn't really surprise me since it said "only applies if the computer is part of a domain" or something like that. I ended up just disabling the lock screen altogether (a setting I noticed when I was wallowing around in gpedit.msc), since the "when no users are logged in" was the only thing I was interested in. I never use the "lock" feature when I'm logged in. Thanks for your help!

It should work whether your computer is part of a domain or not. You might see if restarting the PC after setting the policy may help. Be sure to have the image saved in a public folder so that there will not be any permission issues.
