Windows 11 does not support a “regressive” slideshow (automatically including subfolders) for the desktop background, and the available documentation only describes stable use of the standard background modes (Picture, Solid color, Slideshow, Spotlight) without detailing a known issue where it reverts from Slideshow/Spotlight/Solid color back to Picture.
From the supported configuration perspective, the following are the only reliable, documented ways to keep a specific background mode in place:
- Use the built‑in Personalization settings interactively
- Open Settings → Personalization → Background.
- Under Personalize your background, choose one of:
- Picture – single image.
- Solid color – single color.
- Slideshow – a folder of images (no subfolder recursion is documented).
- Windows spotlight – rotating images from Microsoft.
- For Slideshow, select a single folder that directly contains the images. Windows does not document support for automatically including subfolders in the slideshow.
- Enforce a fixed desktop background centrally (Intune or Group Policy)
If the device is managed (or can be), the background can be locked so it does not change away from the configured image:
- With Intune / CSP (Personalization CSP)
- Create a Settings catalog policy in Intune.
- Under Personalization, configure Desktop Image Url to an
httporhttpsURL pointing to a.jpg,.jpeg, or.pngfile. - Alternatively, use a custom policy with the Personalization CSP:
- OMA-URI:
./Vendor/MSFT/Personalization/DesktopImageUrl - Data type: string
- Value: URL of the image.
- OMA-URI:
- Assign the policy to the relevant devices or users. This pins the desktop to that image and prevents user changes from persisting.
- With Group Policy (on AD‑joined or local machines)
- Open Local Group Policy Editor or edit a domain GPO.
- Go to:
User Configuration\Administrative Templates\Desktop\Desktop. - Enable Desktop Wallpaper and set it to a fully qualified local or UNC path to the image file.
- This also forces a single image and prevents user changes from sticking.
- With Intune / CSP (Personalization CSP)
These management options can keep a chosen background from changing, but they only support a single image (not a slideshow or recursive folder) as the enforced wallpaper.
Windows Spotlight can be configured and controlled via policy (for Enterprise/Education), but again, the documented behavior is that Spotlight or a custom image is chosen and then enforced; there is no documented mechanism to enforce a multi‑folder slideshow or recursive folder selection.
Given the available documentation:
- A slideshow that includes subfolders is not supported.
- A slideshow that sometimes reverts to Picture is not addressed as a known, fixable issue.
- The only supported way to guarantee that the background does not change is to enforce a single image via Intune/CSP or Group Policy.
