What Bluetooth card do you have in your machine, and when were the device drivers last updated? If it's an Intel card they have been churning out update after update for the last several years now and not supplying same to the computer OEMs or Microsoft in a timely manner. There is a strong symbiotic relationship between device drivers and Windows 10 itself, so it's essential to keep both up to date.
