Wow - buried registry key that tells the OS to launch a different process than what was requested.

Thanks Matt!

Debugging application startup when you don't directly launch the app

For reference, if his page is gone, it's here at Microsoft.

And if THAT's gone too, the reg key is here (used by sysinternals.com process explorer to "replace" the built-in taskmgr.exe):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe
Debugger=c:\utils\procexp.exe

in my registry, I have other apps listed that have settings other than "debugger", like "ApplicationGoo", etc. Searched on that setting and found this description of other possible settings.

Maybe I'll add this guy to my news aggregator for a while... :)

(even better)
