Windows Doesn't Detect Intel HD 3000 GPU

I'm running Windows 7 Home Premium x64 on a MacBook Pro using Bootcamp. Recently I noticed that in the Device Manager, Windows doesn't detect the Intel HD 3000 GPU.
I've done some searching online, and came across someone explaining that Apple doesn't allow access to the Intel GPU when using Windows. Though this doesn't make sense to me because Apple supplies the driver for it when you download the required software through Bootcamp.
When I try to install that driver, I recieve an error window: "This computer does not meet the minimum requirements to install the software." Though I've checked all of the requirements and it should install. I believe this is soley because it does not detect the GPU.

Anyway, I'm new here and this is my first question, so if I've made any mistakes, kindly point me in the right direction. Thanks.

If your Macbook Pro has a discrete GPU, the iGPU is disabled and cannot be used in Windows. It has to do with how Apple setup the dynamic GPU switching. The HD 3000 driver is used for systems that only have the HD 3000 GPU and nothing else. While it is downloaded with the rest of the Boot Camp drivers, it isn't used on that machine. There are many other drivers that are downloaded, but not used as well.

That's odd.. Is there any reasoning behind this?

It has to do with Windows being incompatible with Apple's configuration of the dynamic GPU switching.

Oh.. What if I was to use Ubuntu instead? Or does the GPU switching only work in OS X?

Intell said:

The way the GPU switching is setup in Macs will only work with Mac OS X. All other operating systems will see the discrete GPU only.

Oh alright. One more question if you please.. Do you know when using OS X, does the Intel GPU support OpenCL?

I believe it does in 10.9. It might in 10.8 as well.

Oh okay. Thank you for all of the info.
