    Example 1: Stop all instances of a process

    PS C:\>Stop-Process -Name "notepad"

    This command stops all instances of the Notepad process on the computer. Each instance of Notepad runs in its own process. It uses the Name parameter to specify the processes,
    all of which have the same name. If you were to use the Id parameter to stop the same processes, you would have to list the process IDs of each instance of Notepad.
    Example 2: Stop a specific instance of a process

    PS C:\>Stop-Process -Id 3952 -Confirm -PassThru
    Confirm
    Are you sure you want to perform this action?
    Performing operation "Stop-Process" on Target "notepad (3952)".
