Hi Kakosen - Yes, Windows should automatically install the driver for you. Try running Windows Updates and see if a driver is found - http://windows.microsoft.com/en-us/windows7/Update-a-driver-for-hardware-that-isnt-working-properly
If the driver is not found by using Windows Updates, the Asus support site that jefe323 linked you to is the place to turn.
Hope this helps!
