With Windows 8.1, Microsoft has restricted access to the 'Pin to Start Screen' menu command for 3rd party apps. You might be curious, what does it mean? While in Windows 8, apps were able to get programmatic access to that menu item. You might see such behavior in Mozilla Firefox installer: after the install, it "pins" itself to the taskbar. The same thing could be implemented in Windows 8, any app was able to pin itself to the Start Screen. Not so in Windows 8.1.
Why did Microsoft do this? Because they wanted to prevent the Start Screen from getting cluttered. Unlike Windows 8 (which pins everything to its Start screen like a maniac), Windows 8.1 keeps its Start Screen clean. As a result of these changes, the command I mentioned above is now strictly accessible only from Explorer! This is also why my application, Pin To 8, was not able to pin anything to the Start screen.
Today I will show you, how you can extend File Explorer in Windows 8.1 and add the ability to pin ANY file or object to the Start Screen. No 3rd party apps will be required, only a simple registry tweak.
