Hi, good day!
I’d like to ask a few questions first so I can better understand the issue
What is the make and model of your PC/laptop?
Press Start then search System Information
Please take a screenshot of the resulting window
Which Windows 10 version/build are you using? You can check by pressing Windows key + R to open Run then type winver, and pressing Enter.
Do you see the Bluetooth option under Settings > Devices > Bluetooth & other devices?
When did Bluetooth last work properly?
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
