I have no idea what just happened but two nights ago I was using an Xbox One controller to play on my laptop. It was connected wirelessly. However, it wasn't connecting when I tried to the next morning. I found out that the there is not toggle for Bluetooth in the settings. So I went to Device Manager, disabled the driver, then re-enabled it. That didn't work. I tried uninstalling it then rebooting my device. It didn't re-install and it's not showing up when I toggle "Show hidden devices." I looked up drivers online, installed them, but that did not work either. It's as if I never had Bluetooth capability on my laptop.

I am having the same issue since yesterday. Same PC Model, so I believe you are not alone. This seems to be like some corrupt update. Have you figured out what's up with this?
