Custom lockscreen image on creator's update
Hey guys,
So I have a GPO set for our workplace, and have been using this since the original RTM build of Windows 10 back in 2015.
It worked fine on all versions up until the Creator's Update, when it somehow seems to have stopped working, and I can't figure out how to fix it!
It's a two-part process. I have one "preference" set for first user login to copy an image from our SMB network share to the Public Pictures folder (it had to be somewhere they had write access to but was also not going to get in the way or accidentally deleted), as C:\Users\Public\Pictures\Lockscreen.jpg (where Lockscreen is the name of our company, but you get the idea.)
Then, I used this GPO:
Computer Configuration -> Policies -> Administrative Templates -> Control Panel/Personalization -> Force a specific default lock screen and logon image.
I enabled that, and gave it the location to the JPG file I copied via the first step.
The result is that as soon as I join the domain using the computer's local account, the default lockscreen picture goes away, and just shows a solid blue color instead.
Prior to the Creator's update, the first time any domain user logs on, that picture is copied and the setting works correctly - it shows our nice 3D rendered company logo on all the PCs, whether it's the lock screen or the user logon screen.
However - with the Creator's update, it somehow went back to the default image instead! And here's the really weird part... the GPO is still applied, and in Personalization, I see the custom picture selected! It just doesn't actually show it! The file is copied to the correct path, Windows is just ignoring it when I lock the screen or log out.
I can change to one of the other default pictures, and THAT one will show. But as soon as I try to pick the custom one again, it goes back to that default picture.
I can confirm all new installs of build 1703 do this, not just one specific machine. Now, what's interesting is, if I go into personalization and set a custom lock screen (for testing purposes I placed the image on my desktop instead), then DELETE the picture, the lockscreen is still there, despite the fact I deleted the file.
So this leads me to think it's being cached somewhere, and Windows just isn't caching my new image over the original one that was already there before the domain join. It honestly sounds more like a bug than anything, but does anyone have any ideas how I can fix this?
As a manual workaround I can just create a copy of the file elsewhere, and set it as a "custom" lock screen under Personalization (the key to this GPO is that it uses the custom picture as the *default*, which essentially hides that default picture and shows mine instead), but I'd rather not do that if I don't have to.
