Is there anyway to set a program to be unresponsive in windows?

I have python code that starts a program. But when the program becomes unresponsive i want to do some specific clean up task.

But how do I test it. Because currently it is random. Is there a way to either make a small program that I can force to be unresponsive?

Or force a running program to be unresponsive.

An "unresponsive" program is typically a GUI application that's blocked on it's main (UI) thread such that it hasn't pumped messages in a long time. That is, the UI feels "frozen" when you try to interact with it and/or the window doesn't seem to repaint itself as it should.

You can easily simulate this by creating a Windows Forms app in C# or Win32 GUI app in C using the default project templates in Visual Studio. Or basically any UI framework like Qt for that matter. Then introduce a very long sleep statement (several minutes) in response to a button click.

I don't think the "unresponsive" attribute applies to services, console applications, or background tasks.

Use Alt Tab keyboard shortcut to bring your unresponsive program to the front, and then press Alt F4 keys at the same time to force the program to quit.
