Consider the following scenario:
- You install update 2670838 on a computer that is running Windows RT 8.1, Windows 8.1, Windows Server 2012 R2, Windows RT, Windows 8, Windows Server 2012, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1.
- You try to run graphics software or an application that has the hardware acceleration feature disabled. In other words, the application uses software rendering instead of GPU rendering.
- The application uses Windows Advanced Rasterization Platform (WARP) for software rendering.
