After a successful installation of Windows (Windows Server 2012 R2) on a MacBook Pro (Late 2013, 15") I've noticed that only the Nvidia graphics card is recognized in the device manager. So I've tried to install setup.exe from the folder IntelHDGraphics64 which I found on the installation disk created with BootCamp, but I got this error:
"This computer does not meet the minimum requirements for installing the software."
Same error message was thrown when I tried to install the latest drivers from Intel directly.
I even tried to install the drivers manually, but this didn't work either.
Now I would like to know whether it is even possible to get the Intel Iris Pro graphics card running on a MacBook under Windows and then switch between them to increase battery life when I don't need high graphics peformance.
I am using the Mavericks version of BootCamp assistant and have the retina model.

I know this is not the answer you want to hear, but unfortunately there is no way to disable the discrete GPU and use the integrated graphics, when using Bootcamp.
This has been discussed (to death) on support forums and on the web generally.
I have thought myself in the past, that it would be useful to be able to turn off the discrete GPU just to improve battery life on the laptop. But Apple have not provided a driver capable of switching off the discrete GPU, so there is no way of doing it.
Sorry to be the bringer of bad news - who knows, maybe they will provide that functionality in the future?
