As a system administrator, tasklist and taskkill are very important where you could manage them easily from a remote server without access to the remote desktop.
Sometimes, you might suffer from a server highload, you may list the process task list from tasklist from another server,
tasklist /s system /u username /p password
Eg. tasklist /s myserver /u administrator /p mypassword
Next, you may perform a task killing from the taskkill command.
taskkill /f /im process /s system
Eg, taskkill /f /im php-cgi.exe /s myserver
SUCCESS: The process “php-cgi.exe” with PID 4020 has been terminated.
