A spurious dialog box (informative, no?) keeps popping up on reboot.

What's an easy way to figure out what clearly-very-well-coded-piece-of-software threw it up there? I've reduced the startup list to a minimal list to no avail.

Just out of curiosity, what was the program? – VirtualDXS Aug 19 '15 at 3:04

Sysinternals Process Explorer has this feature in the form of a crosshair that you drag over any window or widget.

Nice, thanks! I've been using Process Explorer for years and I never knew about that! – Aaron Miller Jun 22 '14 at 1:19

In task manager, you should be able to right click it and select Go to process, which will open the processes tab and highlight the executable:

If that isn't helpful, Winspector (basically Spy++) can give you a better idea:

Check out Winspector. Install it & run. Switch the Window list's tab to Process. Then drag and drop the red "foresight" from the upper left corner of Winspector onto that dialog box. Winspector will highlight which process owns the message box.

If you are already running AutoHotkey (and if you aren't, why not?) then you could use its Window Spy utility to locate the culprit.
