Hey weissha,
Thank you for using Apple Support Communities!
I understand from your post that you're unable to connect your AirPods Pro's to your Windows PC. I'd be happy to help out.
I'd start with these steps here:
Set up AirPods with your Mac and other Bluetooth devices
You can use AirPods as a Bluetooth headset with a non-Apple device. You can't use Siri, but you can listen and talk. To set up your AirPods with an Android phone or other non-Apple device,3 follow these steps:
- On your non-Apple device, go to the settings for Bluetooth and make sure that Bluetooth is on.4 If you have an Android device, go to Settings > Connections > Bluetooth.
- With your AirPods in the charging case, open the lid.
- Press and hold the setup button on the back of the case until you see the status light flash white.
- When your AirPods appear in the list of Bluetooth devices, select them."
Cheers!
