I'm attempting to set up a shared PC running Windows 11 so that the same desktop wallpaper profile will load, regardless of which user signs in.

I've tried working with the guide at https://www.displayfusion.com/Discussions/View/deploying-customized-settings-to-all-users-on-a-single-machine/?ID=fb7b77eb-7997-4e1b-b91e-0dff1bc1900c, but the desktop background is loading solid black for accounts besides mine (which is the one where I created the wallpaper profile I want to apply to all users and the account where I followed the process linked above).

Any help would be appreciated!

That does work.

But my goal is this: I'm using Google Credential Provider for Windows so that my users can log in to the device with their Google Workspace credentials provided by my school. When a user logs in with their Google Workspace credentials for the first time on this particular device, GCPW creates a new Windows local user profile for that user. I'd like those newly-created user profiles to load the custom wallpaper profile.

Is that possible?
