driver arduino uno r3 windows 8

Okay, so I got a genuine Arduino UNO R3 here. penyebab windows 8 lemot Running windows 10 It is updated I also have the 1 8 13 version of the Arduino IDE All is working well, I then have an issue uploading a sketch to the board and go to the ports tab and see that it is greyed out I look up a solution on these forums that is a few years old that says to uninstall, unplug, replug, then reinstall and that should fix
