Recent versions of PRTG Network Monitor have started including the Npcap driver for packet capture. This driver is causing issues when installed onto machine with 4G connections - disabling their 4G connection until the loopback adapter is disable or uninstalled.

Paessler support have recommended removing the driver and will modify their remote probe installs in future releases of PRTG.

The batch file below will silently uninstall the Npcap drivers.
