Just a f.y.I. for those interested or having driver/graphic issues. Intel just released an updated driver for our HD4000 integrated graphics. Its said to fix alot of bugs in Win8 64bit. Here is the link to the article discussing it. In there has direct link to Intel page with driver download. Also link is there to PDF of release notes. Intel's Updated Graphics Drivers for Ivy Bridge, Haswell Stomps Out Bugs in Windows 7 and 8 | Maximum PC I already installed this in my pro and everything running fine. If you install, you might want to go into control panel. Then windows update. Then turn off automatic update. I have mine set to ask me which ones to install. If not, windows will reinstall that system update from 8/13 and it'll roll back your driver to MS custom Intel driver. This new updated driver, as other generic ones, properly enables the Intel HD4000 Graphics Control Panel. Which can be very useful for fine tuning display, etc... Check.it out. Update: post number 50 has the latest link for Intel generic driver for win 8.1. its for pro 1 and pro2.
