Npcap Loopback Adapter Packet Capture

Just after opening Wireshark, after few seconds, the Npcap Loopback Adapter is showing some activity and in the Packet list section it is showing some data with protocol as ICMP, DHCP, SSDP.

My question is that the Wifi adapter is off and the machine is not connected to any internet. How is it able to capture packets? What are these actually?
