Install Intel Graphics after switching to UEFI

I've got a MacBook Pro Retina Late 2013 which was installed with Windows 10 in MBR. After reading that it is possible to enable auto graphics switching (as it was not possible before) I've attempted to switch the installation manually from MBR to UEFI. Took me a while, but the migration was successful.

I used this guide: http://www.reddit.com/r/mac/comments/3dlu2g/convert_a_bootcamp_bios_windows_inst allation_to

With that being said, I'm still unable to see the Intel Graphics discreet card in my MacBook Pro nor I can find any hints on how to enable it. Are there any pointers I can follow to be able to enable this? With this I'm quite Apple produces good hardware for Windows 🙂.

Thanks!
