Wallpaper Policy Issue

    Question

  • Hi,

    We have applied a policy on the OU to apply a wallpaper from network location like \\Servername\wallpaper.jpg using the User based policy Administrative Templates\Desktop\Desktop\Desktop wallpaper. It is working fine however we have filtered out a group of users from this policy by changing ACL of policy to deny read and apply GPO for this group

    After rebooting the PC the wallpaper becomes blank but after sometime if the user reboots his PC then it again shows the wallpaper.

    We have created another policy and in filtering i have allowed only this group to apply GPO and configured policy Administrative Templates\Desktop\Desktop\Desktop wallpaper to disable but still no help.

    I have checked the path "AppData\Roaming\Microsoft\Windows\Themes" and found a different image file as Transcodedwallpaper.jpg.

    I am not able to understand from where the wallpaper is getting applied. I have thoroughly checked but there is no other wallper policy.

    In RSOP.MSC the policy with wallpaper disabled is showing as applied

    For me, I will clear the key’s value firstly to try it. If it is not working, I would delete the whole key and test again.
    However, serious problems might occur if you modify the registry incorrectly. Therefore for added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

  • Hi,

    This is what I did for our wallpaper:

    1. Create computer configuration policy.

    2. Preferences\Windows Settings\Files\BackgroundDefault.jpg: Update action and source of your network location and destination of %Windir%\System32\oobe\info\backgrounds\backgroundDefault.jpg

    3. Preferences\Windows Settings\Folders\backgrounds: Create action and path of %WindowsDir%\System32\oobe\info\backgrounds

    4. Preferences\Windows Settings\Registry\OEMBackground: Update action and registry entry HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background\OEMBackground REG_DWORD 0x1.

    5. Link the above GPO to your workstations OU.

    Also, the image has to be less than or equal to 256kB in size.

    Hope that helps,

    Vlad

  • Hi Mark,

    I have checked the Patch MS16-072 is not applied on those PC's. Secondly I have observed that once the disable policy is applied on PC a random wallpaper is applied on those. You can change the wallpaper and after changing the wallpaper remains like that.

    I am not able to understand how this random wallpaper is selected and can we force the PC to show no wallpaper instead of random wallpaper so that users can select their own wallpapers  

    Also while searching I have came across a registry key which keeps the history of wallpapers. Will removing that key will help.

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\Wallpapers\Images
