Windows 8, iMac (Mid 2011): Keyboard screen brightness controls do not work

When using Boot Camp 5 and Windows 8 on a iMac (Mid 2011), keyboard screen brightness controls (F1 and F2) might not change the screen brightness.

Instead, use the Settings Charm to control the screen brightness in Windows 8:

  1. Position the cursor in the upper-right or lower-right hand corner of the screen.
  2. When the Charms appear, click Settings.
  3. A brightness icon appears in the lower right-hand corner of the screen.  Use it to control the screen's brightness.
