Older drivers may work fine with older versions of Windows, but they may not work as well with Windows 10. To resolve such issues, go to the Start menu and type Device Manager into the search box. When you click the link, a new window will open with a variety of options. Select 'Sound, video, and game controllers,' and a list of results will appear, including a sound card option.
All you have to do, as per Microsoft, is go to Device Manager (just type 'device manager' into the search/Cortana box next to the Start menu), select the Bluetooth driver, and update it to the updated settings, which are compatible with Windows 10. The operating system should be able to search for and update the driver instantly.
