A wired LAN these days pretty much imply an ethernet switch, ethernet switches doesn't send you any frames that should go to another device if it knows which port that device is plugged into. You can't sniff traffic that doesn't reach your computer - so this isn't related to using Windows or Wireshark. Most managed ethernet switches have a span/mirror port though, where you can mirror all traffic to all ports out on a single port, so you can plug into that port to capture your LAN traffic.
