If you are forced to use Windows for work like me, you should look at Aquasnap. Closest thing I've found to a fully functional tiling window manager for Windows 7 but I am open to suggestions if someone has found something better/free.
Shilling for it because I've been using it for a while on my work machine, but be warned that it is not libre and also costs some dosh for mulit-monitor support.
