This VBscript sample shows how to add the “Pin to Start Screen” context menu item to all files in Windows 8.1
With Windows 8.1, Microsoft has restricted access to the 'Pin to Start Screen' menu command for 3rd party apps. The same thing could be implemented in Windows 8, any app was able to pin itself to the Start Screen, but not so in Windows 8.1. So this script can get the "Pin to Start Screen" context menu item unlocked for every file, and every file system object in Explorer.
