Please Help Installing/Finding Driver

So just received my Arduino UNO in the mail today. Plugged it in, downloaded the driver, and Installed the IDE.

Plugged in my Arduino board and noticed that the on-board LED was blinking 'yellow'. I was curious to why this was so..
I followed this guide > "Getting Started with Arduino on Windows" https://www.arduino.cc/en/Guide/Windows

Made it to the "Install the Drivers" section. Followed the steps and noticed that when I opened up my device manager section my Arduino was labeled as "Unknown Device" under Other Devices with a yellow caution triangle. (pic attached)
Which wasnt a problem as the guide walked me through what to do there. But, as I right clicked on "Unknown device" and clicked "Update driver software" where I was directed to "Browse my computer for Driver Software", I couldn't find the proper Driver File in the "driver" folder!?

I cant find either one it says to click. (ie. "arduino.inf")
I just downloaded the Arduino IDE 1.6.5 and I am running Windows 8

Can anyone pleasssee help me. What do I do to complete my driver installation?
Thank you!

It will ask you to install the drivers at the time of ODE installation
