Microsoft has released Windows 7 Service Pack 1 today. You can download the service pack through Windows 7, or you can grab it from the Microsoft Download Center.
Most of the changes are security patches and bug fixes. But you actually probably already have most of those if you've kept Windows Update running on your Windows 7 machine.
Service Pack 1 does include RemoteFX, which enables 3D graphics for remote users.
