I’m running VS2012 on a Windows8 64-bit computer. I posted this on the Microsoft Windows8 forum, but received no replies. After running the VS2012 update (I started it from within VS and then closed VS) I went to the Start Screen and the icon in the VS2012 tile is now a white square. I unpinned it from the start screen. I typed in "Visual" and found the tile. It had the correct icon on the tile. When I select to pin it to the Start Screen, it still shows a white square instead of the VS icon.
