For example, you can stop a Windows process by using the Stop-Process cmdlet. The cmdlet then uses the Kill() method of the associated process object.

.NET methods can be beneficial for performing operations which have no PowerShell cmdlets. And it can be useful too from the command line; for example, when you wish to kill a process. IT professionals are all too familiar with processes that are not responding and need to be killed, something you can do at the GUI using Task Manager. Or with PowerShell, you can use the Stop-Process cmdlet, as discussed above. At the command line, where brevity is useful, you can use Get-Process to find the process you want...
