***Well nevermind, don't bother reading the post it seems I found the solution in this forum, tried many things from many poster but one of these was to go into the BIOS, turn off WIFI/Bluetooth and reboot into Windows, confirm that WIFI is off (which it was and I also noticed I had no more USB problems). Reboot the computer, go into the BIOS, turn on WIFI/Bluetooth, reboot into Windows and BOOM! Bluetooth is back and working, strange stuff, dark magic stuff (I really don't see why turning the thing on and off in BIOS does anything to Windows) but that thing worked for me at least.***
I've seen pretty much copy/paste same problem on this forum where people had Bluetooth working totally fine and something happens and the icon for bluetooth disappears and after some work trying to remove and install the drivers, in Devices, bluetooth totally disappears and no way to ever get it back or install it back.
Now I had tried many things but this all happened on the 15th of this month when I install 2 updates for WIndows 10 and I did noticed it took a bit longer to reboot in areas where usually updates from Windows will not be able to influence (mainly the part where the BIOS reboots and before Windows starts loading).
Is there a way to manually remove bluetooth drivers? Because no matter what I do, running AsusSetup.exe does nothing (I presume it knows right away that the drivers are installed).
