Dedicated key to toggle touchpad on/off

It seems there are a couple ways to disable and re-enable devices by commandline. Took a little bit to find the ones I recalled seeing. devcon.exe and PnPUtil are 2 options.

Note that both devcon and PnPUtil are windows utilities, not 3rd party applications that one needs to trust & give permisions to which not everyone will be comfitable with.

pnputil /disable-device
pnputil /enable-device

I believe devcon might not be installed by default. windows - Quick Method to install DevCon.exe? - Super User

devcon disable
devcon enable
