I had just an interesting problem: after updating (or being updated) to Windows 10 creators update on my Latitude 5480 notebook I noted some days after, that my bluetooth mouse (Microsoft sculpt) did not work anymore. Looking closer my bluetooth icon was gone on the system. I tried first to update all that can be updated, i.e. first Windows Update, then the dell Command Update utility, but bluetooth kept invisible and could not be started. Finally I found the Bluetooth icon in the Device Manager and de-activated Bluetooth there. Then I activated it again and - oh wonder - Bluetooth started up again, and everything's ok now.
Maybe this helps somebody having the same issue.
Windows 10 Provide driver updates, too.
That could be the Reason why some Settings could change during an Update.
