Windows 10 is not formally supported on older systems equipped with 6 Series chipsets and/or 2nd generation Intel Core processors. See these articles for more information:
What you do have working is as a result of Microsoft's compatibility drivers. These are hit-and-miss, as you have found out.
That said, you could try a driver package like this: Download Intel® Management Engine Driver (5M) for Windows 7*, 8.1*, and Windows® 10 for Intel® NUC Kit NUC5i5MYHE; it might (cross your fingers) provide support this older chipset. If it doesn't; you will just have to leave this device unresolved.
Hope this helps,
