Here is my issue. I have an Early 2015 MacBook pro 13". In Windows 8.1 I had minimal issues and everything was working well. I fresh installed El Capitan on my mac partition and then made sure Windows 8.1 was updated (including all windows based Apple updates). I just updated my BootCamp partition from Windows 8.1 to Windows 10 with no issues. I then updated Bootcamp to the latest version offered by Apple. One that update completed and I rebooted the issue started. I get to Windows login and once past it the screen goes black. system is still operating, but all I can see is my pointer. I tried to download directly from Intel ( I have the Iris 6100), but the result is the same. The only way to keep screen function is to boot into safe mode, rollback the driver to the generic MS display driver, and prevent the driver from re-updating. I even followed the instructions on his page Use Windows 10 on your Mac with Boot Camp - Apple Support but had no result. I reinstalled BootCamp via a USB download from the mac side as well with no result. I also cannot use any external displays with HDMI or MiniDisplay ports in Windows. Mac side works perfect. Help please!
MacBook Pro (Retina, 13-inch,Early 2015), Windows 10, OSX 10.10.1
