(195) Microsoft Intune - Set Lockscreen and Desktop Wallpaper for Shared Devices

Standard wallpaper and lock screen customization via Intune is technically restricted to Windows Enterprise editions. If you’re on Microsoft 365 Business Premium, the Settings Catalog won't work for this.

However, you can bypass this limitation by deploying a Win32 package. Not only does this solve the licensing hurdle, but it also simplifies deployment since the image file is bundled right into the package rather than hosted online.

Prepare the following:

• wallpaper.jpg is the downloaded image that should appear on device’s lockscreens and desktop backgrounds. If you want a different image, then add another .jpg and update the $WallpaperIMG and $LockscreenIMG according.

• Install.ps1

• Uninstall.ps1

• Detect.ps1

Install.ps1:

If you want a different image, then add another .jpg and update the $WallpaperIMG and $LockscreenIMG according.
