Hidden Windows Feature
We don't know what this is supposed to be but I think its an incomplete feature left for some reason. When you hold down Control and click the Taskbar and Start menu item in the Settings Folder, a new hidden tab becomes viewable. Note: This may be a bug.

• Click on the Change Icon to change the icon, and double click the already selected icon, then press OK to exit the properties window.
  
• Go back to the start menu and move your mouse just below Shut Down. A  little arrow should be appear just below it, so just move the mouse over it You will see the start menu slide down a little. And you should see Eject PC (!??).
  Note: This may be a bug. (From- Active Windows)
