Curiouser and Curiouser, said Alice...
So, I had some success. But because MS has Bluetooth settings stuck somewhere in between the old Control Panel and the new Settings interfaces, it's a little weird.
What you need to do is to use what
@Try3 posted to actually get to the Properties, merged into what
@garlin posted,
with a twist.
Part 1, changing the name of your device (from @Try3's post, but most detail):
0. Have your Bluetooth device powered on. If you have not previously connected it, discover it, connect it and verify it's working before starting.
1. Go to Settings >Bluetooth and Devices
2. Scroll down and click on Devices
3. Scroll down and click on More Devices and Printer Settings
4. Right Click on your BT device
5. Choose Properties and then the Bluetooth panel
6. Change the name of the device in the top line then Click OK
Now, the twist:
a. Power your device off
b. Close the More Devices and Printer Settings window
c. Reopen the More Devices and Printer Settings window
d. Turn your device back on. It should show the new name you gave it.
Part 2, preserving the name of your device through reboot (from @garlin's post):
7. Right click on the device again and click "Remove Device"
8. Pair your device to your computer again
9. At this point, in the device selection window it should show the new device name that you just chose
10. If it does not show your new device name that you picked then it didn't work.
11. If it DID show the name you picked then finish the pairing and connect to your device. Go to settings and bluetooth and make sure the name is still changed
If the device still has the new name, restart the computer and after booting, check the device name again to make sure it stuck.
If the device name is still changed then congrats, it worked.
You should be all set.
Part 3, the "other" Bluetooth device name.
0. Make sure your device is powered on and connected
1. Go to Settings >Bluetooth and Devices
2. Scroll down and click on Devices
3. Scroll down and look for your device
4. Click the Drop Down Arrow on the right side.
5. Choose Advanced Sound Properties
6. At the top of the page;
- observe your slightly different generic device name next to the little icon/illustration
- note that it still has the old generic name under it, but ignore that
- Click Rename just below that and rename your device
This rename of the alternative name will stick through reboot without any additional work. The original device name will always be displayed below it and will not change.
There may be some other hoops to jump through and/or alternative paths... but it's late here and I'm done poking around for the night. I'm going to try my own procedure (above) with some additional devices tomorrow. I'll report back.
