I have two issues that can be worked around (this is for the 2006 MacBook 1,1, which requires Windows 10 32-bit). The first is that the Apple Bootcamp drivers refuse to install under Windows 10 due to Apple blocking it - I had to modify the install to bypass the Windows version check.

The main glitch is that the backlight doesn't always activate on login. The first Windows logo appears, but at login the brightness is set to zero. I can type in my password, hit enter & then the backlight activates on logging in. So it's just a glitch, but it is annoying, and I wish either Apple or Microsoft would fix it.

Otherwise, it's fine and everything else seems to work - Boot Camp Assistant works, and even the Apple Remote works to control volume. I don't think I've tried the webcam though. But I have got Cortana to work (even on a 10 year old MacBook!) and it's been fun calling out across the room to ask it questions. It's a little fiddly to get running, but it definitely works.

Thanks! That's really helpful.

Well, I have a better one for you: I am still running windows 7 on an late 2006 iMac. Works like a charm (and better than any version of OSX on it).
