Based on Joey's answer and user's comment.

Assuming that the path of the program is C:\Dir1\file.exe. If multiple instances of the program are running, you should use the following command:

Get-WmiObject Win32_Process |
    Where-Object { $_.Path -eq "C:\Dir1\file.exe" } |
        ForEach-Object { $_.Terminate() }

Otherwise, Powershell will report an error:

PS > (Get-WmiObject Win32_Process |
    Where-Object { $_.Path -eq "C:\Dir1\file.exe" }).Terminate()

Method invocation failed because [System.Object[]] doesn't contain a method named 'Terminate'.

In addition, the above command also avoids the error when no matching process is found (e.g., the Path of no process is equal to C:\Dir1\file.exe):

PS > (Get-WmiObject Win32_Process |
    Where-Object { $_.Path -eq "C:\Dir1\file.exe" }).Terminate()

You cannot call a method on a null-valued expression.

If you don't like WMI:

Get-Process |
    Where-Object { $_.Path -eq "C:\Dir1\file.exe" } |
        ForEach-Object { Stop-Process -Id $_.Id }

I noticed that the Win32_Process.Terminate() and Stop-Process methods are used to forcibly terminate the process, so the process may not be able to perform any cleanup work.

Tested in Powershell 2.0 on Windows 7 SP1.
