The CD that came with the device listed RTL8671B, but it's not on Realtek's website. Instead the manual points you to:

Direct download and the popup window for 1.6.1015.3014
didn't initially work. I ended up needing to right click the link and select Save target as
.
For it to work for me on Windows 10, I unzipped the cab file into a folder and then used Device Manager to look at that folder. Worked like a charm.
Thank you.
Please note that x.x.1051.xxxx is also for Windows 10 x64.
I've downloaded this one and it works:

The driver works with my BT dongle with PID 0BDA-A725 (USB\VID_0BDA&PID_A725&REV_0200)
I had to force the installation as you have mentioned).
Side note: When a BT device is connected, AIDA64 is saying the radio is 5.1.
It's also the case with the previous driver, 1.9.1051.3004, (BT 5.3) that was installed by Windows Update.
Is there any pro or cons to use the newer driver instead of the previous one ?
