# Touchscreen-Toggle (PowerShell version)
# This script toggles the touch screen interface (in Windows, it's a "device") on the Windows client between enabled and disabled states
# This preserves digitizer stylus input for drawing, while eliminating false finger/hand touch input entirely when disabled
# Created by Amphyvi
