I need to install my Arduino drivers, but Windows 8.1 doesn't seem to like Arduino, and it greys out the update driver button. Therefore I can't select the drivers from the drivers folder in my Arduino IDE folder.
There are drivers that need to be installed. But Windows 8.1 greys out the update driver software button. Also, it refers to Arduino Uno as an unknown device. How do I install the Arduino drivers and make Windows let me install the drivers?

1I've fixed the problem now :). The drivers needed administrator rights for modification and I'm not admin so I asked my admin to allow me to update the driversuser15851– user158512016年09月14日 21:49:37 +00:00Commented Sep 14, 2016 at 21:49

The IDE package usually ships with the driver(at-least the latest one).
Go to Program Files in C: and find the Arduino folder and you should find a folder named Drivers. Inside you will find an application named dpinst-x86. Run it and you should be good to go!
Often reinstall the latest arduino IDE with Windows Administrator rights helps (use right click execute as administrator).
If the arduino is undetected in PC go to control panel-device manager - connect the arduino and some COM port will appear click it and troubleshoot make sure your PC is connected to internet and then you will be able to see your com port in arduino ide.
