Update: The guide below was written for Windows 8 Developer Preview and will not work with the Windows 8 Consumer Preview
released on February 29th, 2012.
But you
can still enable Metro style apps on Windows 8 Consumer Preview — you just need to download a graphics driver that lets you adjust your screen resolution from the
Intel download center.
If you have a netbook with an Intel Atom N270 or N280 processor, after installing Windows 8 Consumer Preview, search for the download center for the latest graphics driver for GMA 950. If you’re using a netbook with an Intel Atom N450, N455, N550, or N570 chip then you’ll need a driver for GMA 3150 graphics.
