[SOLUTION] Black Desktop Image after applying Desktop Image via Group Policy
In Windows 7, group policy that is set to change the users desktop image, can on some occassions be rendered black. Regardless of using Active Desktop or not.
For some of us that have experienced this annoying "Feature", I have come across a simple solution that solves this issue. Last I heard MS was creating a hotfix to sort this problem out.
Using Server 2008 style group policy preference settings we can modify the registry settings much more easily. You can create this registry setting by modifying the group policy directly on the 2008 server or using Win 7's Group Policy Management.
User/Computer configuration > Preferences > Windows Settings > Registry
Create an registry setting to HKEY_CURRENT_USER\Control Panel\Desktop\ and modify the value Wallpaper (Value type: REG_SZ) to the location of your background picture.
That should then display the desktop background correctly.
