Hi @s12827 - Is your webcam listed under "Imaging devices" in Device Manager? If so, what is the name of the webcam device?
RIght-click on it and choose "Properties" from the popup menu. Choose the "Drivers" tab. What developer and version is the current driver for this device.
Uninstall the driver from Device Manager and reboot, does Windows install its Plug N Play driver and resolve your issue?
