Windows 10: Missing of Bluetooth in device manager

I am facing problem of my laptop Bluetooth. Initially, the problem is that my Bluetooth device cannot connect to my laptop and my Bluetooth button in the setting was missing. After trying fix it in the device manager, it was showing that error code 45 which I have to reconnect with the Bluetooth hardware but I never eject any hardware from my laptop before. Anyway, by following the instruction, I tried to uninstall the Bluetooth driver and it should be reinstall after restarting but it didn't happen.......even after I pressed for "scan for hardware changes" in device manager. So what should I do now?

bluetooth missing in device manager

I upgraded my Toshiba L50-B-1NL to Windows 10 yesterday and I now find that my Bluetooth mouse is not working (it was absolutely fine in Windows 8.1). On checking device manager, I find that the Bluetooth is completely missing in the alphabetical list.
I cannot seem to find any assistance anywhere on how to resolve this problem. Can anyone help?
