In case you have this problem. you are not the only one.
My blue tooth speaker was no longer matching with my laptop although it had been the day before.
The blue tooth icon was also not showing in my Notification Area.
To repair this, type in device manager it should come up first, click it to open the interface. Your Bluetooth will be listed but will probably have an exclamation mark showing a problem.
Right click this and choose Uninstall. Now close Device Manager and restart your laptop. It will rediscover this service and repair it.It should now be visible and any speaker attached turned on will now match.
This is probably a driver issue when Win10 updates, it has happened a couple of times, just another....
