Only a few games can be activated through Steam via a CD key or something like that. Valve games are the big one, bit I believe there's another company as well.

But if you bought the game via retail box, you'll just have to install it to Windows and live Steam-less.

Only certain games can be activated on Steam. Here's the info from Steam support:
