Is there a way to use the Windows GUI (not the command line) to close all copies of a particular running application, when the Taskbar is set to "Never combine"?

The fewer clicks and/or keystrokes, the better. (For example, one solution would be to individually close each application window, but a quicker way to do this is what I'm after.)

I'm running Windows 8.1, but I would be interested in answers applicable to any recent version of Windows.

  • Doesn't the Task Manager do what you want? – Ramhound Apr 2 '14 at 15:49
  • @Ramhound I don't believe so. For example, if I have 5 instances of notepad.exe running, and I want to close them all, if I use Task Manager to kill one of those applications and/or processes, the other 4 remain open. I'd like to have a way to close all 5 at once. – Jon Schneider Apr 2 '14 at 15:50

    Before you say "Answers on that duplicate talk about the command-line when I want GUI": a) it's the same question (even if you don't like the answers), and b) the accepted answer is suggesting creating a shortcut to run a command, therefor making the command into a clickable GUI item (a shortcut). :) – Ƭᴇcʜιᴇ007 Apr 2 '14 at 16:49

    @techie007 (and users who are voting to close this), this question is different in that it's asking for a method to close instances of any arbitrary Windows application (not necessarily known beforehand) -- not always notepad.exe (or some other specific application that can be hard-coded into a shortcut) as in the linked question. – Jon Schneider Apr 2 '14 at 17:52

Here's a PowerShell script you can play with.

Currently it makes a form that has a button for each active Process name.

Click the desired button and all processes with that name will be killed.

Add-Type -AssemblyName System.Windows.Forms 

$Processes = Get-Process | Select-Object Name -Unique

$Form = New-Object system.Windows.Forms.Form
$Form.Text = "Multi-Process Killer"

function KillProcs($ProcName) {
    Stop-Process -processname $ProcName

for($x=0; $x -lt $Processes.Count-1; $x++){
    $Btn = New-Object System.Windows.Forms.Button
    $BtnSize = ($x*24)+4;
    $Btn.Location = New-Object System.Drawing.Size(10, $BtnSize)
    $Btn.Text = $Processes[$x].Name
    $Btn.Name = "btnKillProc$x"
    $Btn.Size = New-Object System.Drawing.Size(200, 24)
    $Btn.Add_Click({ KillProcs($this.Text) })


If I had time, I'd replace all the buttons with a scrollable, selectable listbox and a single "Kill" button, but this should be enough to point you (or someone) in that direction I'm sure. :)

  • Nice! I gave this a try and it does work fine on my Windows 8.1 system, albeit with the limitations that you alluded to, like lack of a scrollbar to scroll through the long list of processes. – Jon Schneider Apr 4 '14 at 18:20
