You see a black desktop background after the computer switches between graphics adapters in Windows 7 or in Windows Server 2008 R2

Symptoms

Consider the following scenario:
  • You have a computer that is running Windows 7 or Windows Server 2008 R2.
  • The computer has multiple graphics adapters.
  • You enable the desktop background slide show to display dynamic desktop backgrounds (wallpapers) on the computer. For example, you apply an Aero theme that contains multiple wallpapers.
  • The computer switches the display from one graphics adapter to another.
In this scenario, a black desktop background is displayed instead of the specified desktop background.

For example, you have a portable computer that includes two graphics adapters:
  • A high-powered graphics adapter that is used in the performance mode.
  • A low-powered graphics adapter that is used in the power-saving mode.
After the computer switches from the power-saving mode to the performance mode, you see a black desktop background.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.1.760
    0.16xxx
    Windows 7 and Windows Server 2008 R2RTMGDR
