  2. Select Hardware and Sound


  3. Select Device Manager


  4. The Bluetooth driver should be located under Other Devices

Kudos to the person(s) responsible for writing the instructions for troubleshooting missing driver/update. I am 75 years old and what a pleasant experience I had following your so-easy-to-follow instructions and getting Bluetooth back.
I am a happy “camper” once again.
