If you having a Bluetooth error code 10 after windows update here is something for you
I found a fix uninstalled ur Bluetooth driver, disable fast startup in power setting and then turn of your computer for 5 sec and turn it back on, Windows 10 will auto reinstall driver for you when your pc turn back on if not download the driver and install it urself. I believe fast startup doesn't turn off your pc completely when you restart or shut down and that's what costing the problem.
Credit does not go toward me, I found this somewhere else when I was searching on my phone but I forgot where.
and now I'm just sharing this everywhere because it was a pain for me when my Bluetooth didn't work after the windows 10 update and I try everything that internet has to offer but finally here something works
