Just wanted to say that my Bluetooth also stopped working this week, Ser5 Pro. Had no problems up until then. New window updates would resolve it but its back to failing. I will try these steps provided. Thanks.
Edit: My Bluetooth is now working with these steps.
Resetting the CMOS did not help. I ensure to start the services and then ran Bluetooth diagnostics, Despite the troubleshooter being unable to full resolve the issue. The problem seems to be fixed for now.
Thanks!
