I got this update and would prefer to uninstall it.
Intel - System - 3/13/2016 12:00:00 AM - 11.0.0.1010
Thing is, I can't find the hardware it is related to in Control Panel -> Device Manager, so I can't roll it back. Searching the registry for the driver ICCWDT, it seems to be related to ACPI. One entry showed that the the MatchingDeviceId is acpi\int3f0d and it seems to be called Intel Watchdog Timer Driver. I see no references to that in startup or services (using msconfig).
Was it an update that installed a driver that was not relevant to my machine, so there is nothing I need to do to "undo" this update?
