Um… that approach IS used for applications. If you uninstall Word and reinstall 
it, your Word preferences persist, and your Word documents are still there.

Hello Matthew,

Have you tried adding uniquifying information into the reference string as 
suggested below?

This might help but it would be an extremely ugly solution.

As you know, Windows 10 just collects audio device/driver instance
information, and never deletes it on their uninstallation. Once
installed, device/driver information remain in the Registry forever. I
believe that this approach is fundamentally wrong, and in fact is a
crutch that supports some internal system flaws.

Just imagine that the same approach is used for applications. Once
installed, every application gets registered in a system database, and
the system uses database records to modify some application
properties, out of your control or even awareness. If you uninstall
the application, all database records persist. If you install the same
application again, even years later, the system recognizes it, and
used its collected data to modify application's behavior again, out of
your control or awareness. You have no opportunity to clear these
records, except of dirty hacks. The only way to get a "clean"
application behavior is to change its version, even if no
modifications were made to the application itself. I don't think you
like this behavior of the system. :)

Regards,
Eugene
