Description
Windows 10 Ent 1909
I have just upgraded Wireshark which provides Npcap 1.0.0. Wireshark doesn't show any network interfaces and Npcap doesn't start. Here is the error from Windows event log.
"The Npcap Packet Driver (NPCAP) service failed to start due to the following error:
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."
Any idea what the issue is?

Research direction
Start with the Windows event log message and the Npcap 1.0.0 upgrade context on Windows 10 Enterprise 1909. Investigate why the NPCAP service's digital signature is rejected and verify the result by confirming that the service starts and Wireshark shows network interfaces.
