Windows – How to determine what process a window belongs to


Every time I start up windows vista lately, I see a random floating window. It is a tiny little window with no title, and only the resize, maximize and restore buttons. I'd post an image, but I don't have reputation here yet.

I can close it, and it does indeed go away, but I would love to figure out what it is and stop it from popping up at all. I used Autohotkey's window spy on it and all I learned is that it is a swing window, which doesn't help me out a whole lot.

Is there a good way to identify which process it belongs to and figure out how to kill it?

Use Process Explorer, it allows you to identify the window and then you can check the properties of the process to figure out the command line used. This command line will help you determine what exactly has been launched, this helps to figure out where Java applications and scripts are located...

Just drag the icon over the window.
