Windows 8 Newest Intel Graphics Drivers

The link you provided seems to direct to the Intel Graphics drivers download page. These drivers were likely the latest ones available as of 10/23/2012. Considering that the official release of Windows 8 was scheduled for that Friday, it's plausible that these drivers could have been intended for the released version of Windows 8.
If you are looking to update your graphics drivers for Windows 8, it's recommended to visit the official Intel website or check for updates through your device's automatic driver update feature, as newer versions of the drivers may have been released since then.
