Someone please tweet that at him. It's really dumb that Windows hasn't embraced its open nature to act as a management service for all the digital distribution platforms I use. It would be nice to know what games I have on each service without having to launch them all individually.

If you don't know, Steam does have "Non-Steam" games, you could always add them into your steam library like that, you even still get the overlay, screenshots etc.
Of course though, this does require you to have them actually installed.
