Bluetooth headphones won't reconnect to XPS 8900

Seems like I'm getting the same issues with my other set of bluetooth headphones, so it's definitely not a Bose issue.

burnsider,

Have you tried updating your QC 35's software?

The current version is 1.0. You can click the link below to update.

Yes. I'm at the latest version which is 1.0.6.

burnsider,

1. Pair your device, confirm that it is working
2. Disconnect your device, connect to something else and confirm that you are not automatically reconnecting to windows.
3. Right click on the speaker icon in the lower right corner of the screen.
4. Select "Playback Devices"
5. You should see your paired devices in here.
6. Right click the paired device and you will see "Test, connect, disable, set as default...etc etc etc.
7. Click "Connect" at this point.

Informatiojn from Bose Website Below.

When powered on, the headphones try to reconnect with the two most recently connected devices. Make sure the devices are within range and powered on with Bluetooth® enabled.
If the device you would like to connect to is not one of the two most recently connected devices, follow the steps below to connect to another previously paired device.
Slide the power switch to the Bluetooth symbol then release it to hear which device is connected.
Within two seconds, slide the power switch to the Bluetooth symbol and release again to connect to the next device in the headphone pairing list. Repeat until you hear the correct device name.
Play audio on the connected Bluetooth device.
Note: The headphones can remember up to eight paired Bluetooth devices in its pairing list and can be actively connected to two devices at a time.

Thanks for your help Jesse. Bad news is that Windows 10 is not even finding any bluetooth devices now. I can pair the headphones fine to my phone or other Windows 10 PC, but this PC now is not even finding any bluetooth devices that are in pairing mode.
