Identification of Process for termination

Yes, I need to basically find the process associated with it .

So Can you plz highlight on the part : every window and then check each to see if it has an open dialog box
How can we achieve that?
I did get the list of process via Get-Process but didnt find any unique attribute within the result set to identify it as an Open dialog box

And using this command :
Get-Process | Where-Object {$_.MainWindowTitle -ne ""}

 
doesnt fetch the result because I tried terminating all processes with the output of above query and the window/pop up was still there

You're assuming that what you posted in your initial question is something associated with a process that has a "window" with a title bar. My answer was using your assumption to look for a "Dialog Box" that's associated with a process with a "Window".

"Get-Process" probably isn't going be helpful. Have you looked at the UIAutomation module? You can find helpful answers and (probably) code online. If you can't find what you need, try asking an AI like Microsofts' Copilot (or ChatGPT). Even if the answer you find doesn't directly address your question you can refine the question and ask again. Most often you'll find at least a starting point to dig deeper. Reading the AIAutomation modules' "help" will aid you in understanding any answers you get.

It's not an automated solution, but you could use Process Explorer.

Click and hold the target icon and drop it onto the dialog box. Procexp will highlight the process.

I'm gonna take a guess here and say that it'll show it's the Edge browser process. I say "guess" because I don't know if he can Alt-Tab to that dialog box. For alt-tab to work the window needs a window handle for it to be included in the Z-Order. If it's a modal dialog box the focus is managed by the application.

I'm also gonna guess that because this happens "sometimes" that the reason for the dialog is that the session (between the desktop app and the app on the server) has expired. If that's the case, killing the dialog box won't do much good.

Again, those are both just guesses.
