If you have a network device driver with an unsigned co-installer and you use the Windows XP operating system, you cannot disable or enable the device from the Network Connections folder (that is, you cannot right-click the device and then click Enable/Disable).
You can, however, enable or disable the device from the Device Manager.
The Device Manager runs in the logged-on user context and is, therefore, allowed to disable or enable devices with unsigned co-installers. However, the request from the Network Connections folder to enable or disable devices is sent to a LocalSystem service, which is not allowed to enable or disable devices because an unsigned co-installer cannot be trusted to run in the logged-on user context.
