Although it's one card, the WiFi and Bluetooth functions may actually be two devices with separate device drivers. I'm pretty sure on my system with those functions included on the mobo using Intel chips, I get frequent driver update messages for the two devices separately. If you do not see the Bluetooth item in Device Manager, Windows has not detected it OR has not been able to find the correct device driver for it for use in Win 10.
Try this. FIRST try to find the website for the maker of that card, and look there specifically for a Bluetooth driver for Win 10. If you find one you can download and stash someplace you know it should be. IF it comes also with installation instructions, that would help.
On the other hand, if you can't find a driver there or have no installation info, try this. In the search window at bottom left type Device Manager, then click on the listed item in the pop-up. Click on the name of your system at the very top of the list. Then Choose from the top menu Action ... Scan for Hardware Changes. This will force Windows to re-scan your entire machine and hopefully find the Bluetooth device. IF it knows what that is, you can let it do its own search for a driver and install that. Or IF you have the drive already by download, you can tell Windows not to search, and just install the driver you have. If this works well, the device will be listed in Device Manager with NO Yellow caution sign on it.
