I need to disable the Windows key on a Microsoft Surface 3 running Windows 8.1. I found a registry tweak that disables the functionality of the Windows key. In other words, the Start screen no longer pops up when I tap the Windows key. However, even with this tweak enabled, the tablet still vibrates when you tap the Windows key. Nothing happens besides this innocuous vibration, but I'd like to disable that, too. How do I disable it completely?
