List of installed apps in Windows?

[Scott R Ehrlich]

Is there a utility which can query a Windows machine (NT 4.0, 2000, XP) and
produce a list of installed applications?   Not all programs register with
Add/Remove programs.   Some simply end up in Start > Programs.

The idea, as well, is to find a utility (even within Windows itself) to produce
such a complete list, but that does not actually get installed on the machine.

Belarc Advisor is the only other utility that comes to mind, but it gets
installed.

There is a Windows registry key to list programs that have been installed and
can be uninstalled, but again, not all programs properly register themselves
there.

Thanks for any leads.

Scott
