So this interesting. We have our first desktop added into InTune that is running Windows 10 Tech Preview. In InTune it does not display as "Windows 10" as I would have expected. Instead it displays as "Windows 6.4" which is slightly confusing as the kernel is "NT 6.4" and the name is "Windows 10." Blending the two is odd.

Just found it interesting.

I've seen this behavior before - I think it was WSUS - windows 8(.1) was reported by something than it's normal name.
