There are set of Windows DDK API there, by using them we can enumerate
all the Devices and once we get the required Device we can change the
properties of the device (Enable / Disable) and update the Device. One
should have Admin previliges to do this. Please look at the Microsoft
Documentation for
SetupDiGetClassDevs, SetupDiEnumDeviceInfo and other APIs for more
information.
