When you install Win 8 on a Netbook the screen resolution would be too low for Metro apps to run which is a bummer. One way to get around this and “fix” this is to update the registry (and you thought that was so XP!) :).
Run Regedit and search for “display1_downscalingsupported” (without quotes). Find all occurrences of this entry and change its value from 0 to 1.
Reboot when finished and you should have more options on your Screen Resolution choosing which will allow you to run Metro. 🙂
