Kill process on port on Windows

I would like to create an alias for finding process on specified port and an alias to kill process by PID.

1. Create an alias.cmd file in %USERPROFILE%
   

   notepad alias.cmd
   

   then add the following three lines to the file:
   

   @echo off
   DOSKEY proc=netstat -ano ^| findstr :$1
   DOSKEY kill=taskkill /F /PID $1
   

   The first alias proc accepts one argument and lists PID of process running on that port.
   The second - kill (which also accepts one argument) - terminates the process by PID.

2. Run regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor (for MS10), HKEY_CURRENT_USER\Software\Microsoft\Command Processor (for < MS10). Add String Value entry with the name AutoRun and value %USERPROFILE%\alias.cmd (path to .cmd file).

Now I can start cmd, type proc 8080 and then for example kill 15003.
