Hi,
my singleboard dual Atom PC runs 32bit Windows 7 and loads the ESS plugin, although if memory serves it has .net4.....its been six-seven years since I installed it.

Certainly Mach and the ESS will run on Windows10. If the PC is never connected to the internet, and that is recommended for a machine control PC, then you'll never
have to worry about updates screwing up your machine.
