Bluetooth error, Bluetooth adapter missing from device manager. Unknown USB device with yellow exclamation mark. Windows 10

After 2 years my Windows 10 having bluetooth issue,
sometimes bluetooth suddenly missing in the middle of being used to listen to youtube.
Sometimes it can be fixed by removing unknown USB device from device manager and clicking refresh. But most of the time it doesn't work.
Unknown USB device keep reappearing after being uninstalled.
Clicking detail in device manager shows error COM3 Unknown USB device for task printing via USB.
Removing printers doesn't work.
Restarting with no services and autostart programs also doesn't work.

Today the one thing that work (and hopefully permanently) is updating intel driver via

It's the new (Nov 2017) inter drivers update assistant, replacing older IDUU.
