This technique is only suitable for Advanced Computer Users and Hackers, but it should stop Steam using any excess memory at all. You'll need to apply it every time you finish using Steam to play a game.

WARNING: BACK-UP YOUR FILES BEFORE ATTEMPTING.



Yep.

But seriously, without this thread I didn't know about P2P issues. I don't see why I would possibly want it leaching any bandwidth or acting as a P2P when I've got no downloaded games anyway, but I'm glad I know now.

You may have installed your current game from disc, but now that its registered with Steam, you can download it as often, whenever, and wherever you want. As long as Steam is alive, you don't need the disc.
Not to mention the automatic updates Steam takes care of (depending on developer support).
