 To get a list of bound ports in use, try this PowerShell command line:

Get-NetTCPConnection -State Bound | ForEach-Object {$p = (Get-Process -Id $_.OwningProcess);New-Object -TypeName psobject -Property @{ "LocalPort" = $_.LocalPort; "PID" = $p.Id; "ProcessName" = $p.Name; }} | Format-Table -AutoSize -Property PID, ProcessName, LocalPort

or you can also use

The command "netstat -anob" shows all in-use ports
