I have Surface headphones running on my Surface studiio 2.
As of the latest update I have been having constant problems with the headphones disconnecting and then reconnecting randomly throughout the day. No apparent cause, used the bluetooth wizard helper etc but nothing solved the issue.
Then while looking through my installed app list I spotted Skype an application I had removed well over a year ago. Windows update had re-installed it (along with a bunch of other **** I didn't want !! .. stop doing that Microsoft !!).
Deleting Skype completely solved the issue, surface headphones now working as intended with no drop-outs or disconnection.
