Problems with driver (greyed out port)


A few hours after having plugged in my Arduino to my computer with the USB, it stops recognizing the port (greyed out in the IDE).

On any windows 10 computer that I test, the ATmega16U2 DFU is filed under ‘Other devices’ in Device Manager. I understand that it is supposed to be under USB controllers (see attachment)?

Windows can’t find the drivers both online and when I select them manually they fail.
I read something about burning the drivers onto the chip (here), but honestly I’m not sure if that is the proper way to update the driver.
How can I get my drivers for the Arduino working properly again?

System: Windows 10 64 bit
Arduino: Arduino UNO R3
Chip: ATmega16U2
IDE: 1.8.3

Thanks in advance,
