Per Microsoft, Windows 7 support expends until 2020. But if it's anything like MS XP, support will continue long after the official expiration date. I'm still getting XP updates even this week on older systems, years after they "stopped support."
I see no need to dump a motherboard that works and is stable. It may not be the fault of the motherboard as much as Windows10 or a C602 faulty driver. There is no fault on the board, just the inability of Microsoft to provide support for already operational hardware and not supporting a conversion to their latest O/S. The reputation MS has for releasing immature operating system is legend. They work out bugs as they go. A fix will probably be developed as W10 matures. And if not, W7 is a stable operating system that will be around for years to come.
