How do I unpin a Tile in Windows 8?

You can unpin a Tile or even multiple Tiles at one time from the Start Screen.

1. From the Start Screen, right-click on the tile(s) you wish to unpin. A bar at the bottom of the screen is displayed.
   
2. Click Unpin from Start. Notice that the app(s) you have Unpin from Start is now removed from Start Screen.
