Looking for recommendations on the most reliable method to change the desktop wallpaper on Intune-managed Windows devices.
Current setup:
Created a Win32 app using PSADT
Tested running as both SYSTEM and USER
Wallpaper image is included in the Files folder and copies successfully to C:\ProgramData on all devices
However, the wallpaper only applies on roughly half the devices consistently
Constraints:
We do not have a public/internal URL available for the image
Cannot use Blob Storage or web-hosted images
Has anyone implemented a fully reliable / “set-and-forget” method for deploying wallpapers in Intune under similar constraints?
Interested in:
Win32 app approaches
Proactive remediations
CSP / Policy methods
Registry-based solutions
Anything proven stable across Windows 10/11
Would appreciate examples or scripts if possible. Thanks!
