Yes - ideally, this should be resolved as a system deployment approach, but the corporation that controls the system (Microsoft) have little interest in deploying opengl drivers to the system.

I therefore don't think this can be resolved as a system deployment approach, since ANGLE/llvmpipe is not part of the OS graphics stack on windows. When I install a new graphics card (or even just upgrade the graphics card driver), I expect that the software on the system will automatically take advantage of its new capabilities next time it is started.
