Check all windows port status:
netstat -ano
protocol type, ip address + port number, transmitted to the external address, status, i.e. the PID process ID.
We want to filter out the port: as 443
netstat -ano | findstr "443"
to find the corresponding PID, such as the first line corresponds to 8776, with process ID 8776, indicating that the process is occupying the port.
Find the occupied program:
tasklist That list all running processes, | followed by filtering criteria.
tasklist | findstr "8776"
results are shown, program or my vmware.
