Hello, thank you for reaching out to Microsoft Q&A.
May I please know if you're able to connect other Bluetooth devices?
And, did you put your AirPods Pro into pairing mode?
Press and hold the button on the back of the AirPods Pro until it blinks white. If it blinks white, it means it is in pairing mode. (or you can reset it until it turns Red)
- Go to Bluetooth settings on your Windows PC, select "Add a Bluetooth device," then choose "Add."
- This will search for nearby Bluetooth devices. Select your AirPods Pro from the list and click "Connect."
