Unsuccessful USB Uploads

I'm trying to upload using a USB port, but I don't have the correct drivers installed. I'm using an UNO and I've followed every step on the HowTo page, but it's still unsuccessful. I don't have the arduino.inf or the Arduino UNO.inf file in the "Drivers" folder to update the port correctly. I've downloaded the IDE again and there is still no file. If it helps, I'm using Windows 8.

The file you need to find in the “drivers” folder is actually Arduino.inf

The easiest way to go about installing the drivers is by using the “Update Drivers” feature in Device Manager. Using this you would only need to point the Wizard to the Arduino install folder whiole allowing it to search sub-directories.
