Windows registry and being a "proper" app

[Ray Bennett]

Okay, I've not really ever done any development for Windows-resident 
apps, so forgive my ignorance on this one.

Is there anything I need to do to make my application "proper" as far 
as Microsoft is concerned?  Specifically, is there something I need to 
do in order to get it checked into the registry, etc.?

What's different on XP in this regard?

Thanks for your support.
