There are numerous methods to set a desktop background on Windows. It is possible to set desktop wallpaper using Group Policy and Registry Editor. However, if you have done everything correctly, but it is not working, follow these suggestions. Before getting started with these solutions, make sure you sign out of your account and re-sign in. It is essential to do so after changing the wallpaper using the Local Group Policy Editor or Registry Editor. If you don’t do it, your wallpaper won’t get updated.

Desktop Background Group Policy not applying

To fix Desktop Background Group Policy not applying error in Windows 11/10, follow these steps- Let’s check out these steps in detail.

1] Verify Registry Editor settings

As it is possible to change the desktop background using Registry Editor, it is essential to verify the Registry Editor settings. If you have set something in the Registry files and are entering something else in the Local Group Policy Editor, it might not work because of some internal conflicts. To get started, open Registry Editor on your computer and navigate to this path- If you find a sub-key named System, open it and check whether there are two String Values named Wallpaper and WallpaperStyle. If so, right-click on System and select the Delete option.

Following that, confirm the removal. Then, follow the same steps to set wallpaper using Group Policy.

2] Check wallpaper path and name

When you use the Desktop Wallpaper setting in the Local Group Policy Editor, it is mandatory to enter a path defining the wallpaper. Later on, it cannot be changed anyhow. If you move the wallpaper file from one place to another, it is imperative to change the corresponding Group Policy setting path. Similarly, if you change the name of the wallpaper file, you have to do the same. Otherwise, you will see a black or blank desktop background next time you re-sign into your user account. To verify that, open the path where you have kept your file. Then, open the Local Group Policy Editor and navigate to this path- Double-click on Desktop Wallpaper setting and enter the new path before clicking the OK button.

3] Rename TranscodedWallpaper

In simple terms, you have reset the wallpaper cache on your Windows 10 computer. For that, two files are responsible, and one of them is TranscodedWallpaper. Therefore, press Win+R to open the Run prompt and enter the following path- Here you can see a file named TranscodedWallpaper. Right-click on it and select the Rename option.

Then, enter a name like TranscodedWallpaperOld or anything else.

4] Delete content of slideshow.ini

The second file responsible for the wallpaper cache is slideshow.ini. You will see this file in the same location as TranscodedWallpaper’s. Therefore, open the File Explorer and navigate to this path- Before doing this, don’t forget to show hidden files and folders. After opening the Themes folder, you will see the file called slideshow.ini. Right-click on it and select the Edit button. If you see anything in the file, select them all and delete them before pressing Ctrl+S to save.

5] Check the Prevent changing desktop background setting

Suppose you cannot change wallpaper in Windows 10 in any way. In that case, it is essential to verify the Prevent changing desktop background setting in the Group Policy and the similar value in the Registry Editor. To get started, open the Local Group Policy Editor and navigate to this path- Double-click on the Prevent changing desktop background setting on your right-hand side. If it is set to Enabled, choose the Not Configured option and click the OK button.

Similarly, you have to verify if there is a corresponding Registry value or not. If yes, it can cause the same issue. For that, press Win+R, type regedit, and hit the Enter button. Then, press the Yes button in the UAC prompt to open the Registry Editor on your computer. After that, navigate to this path- In the Policies key, you will see a sub-key named ActiveDesktop. If you can see it, you will also find two DWORD (32-bit) Values called NoAddingComponents and NoComponents. Double-click on each of them set the Value data as 0, and click the OK button. Alternatively, you can right-click on ActiveDesktop, select the Delete button, and confirm the change. That’s all! Hope these suggestions work for you.
