Q: I'm having trouble installing windows 10 upgrade on my Mac Mini with Iris graphics
I'm running OS X Yosemite 10.10.5 on my Mac Mini with Iris Graphics. I've been running Windows 8.1 in Boot Camp without any problems. I have followed the steps outlined here Use Windows 10 on your Mac with Boot Camp - Apple Support
If I run the upgrade adviser in Windows it identifies a problem with my Logitech mouse, but says everything else is fine. So I run the update. Except now it says that the Iris driver is not compatible and refuses to upgrade to Windows 10. The graphics driver there is currently for an Iris 5100 10.18.14.4264. I know this isn't the official driver for BC, but when I got the initial fail I tried updating it. Running Apple update in Windows says that the driver is current and doesn't replace it.
I've tried forcing the driver to version 15.40.7.64.4279, which doesn't officially support 8.1 but does support 10. Doesn't work. I'd like to roll the driver back to the BC version 10.18.10.4242, but don't know how.
Mac mini, OS X Yosemite (10.10.5)

Please see Boot Camp: Solve Windows support software installation problems . This is what I was referring to in your other thread.
