On February 16th, Service Pack 1 for Windows 7 and Windows Server 2008 R2 was released to TechNet and MSDN subscribers. I took some time this morning to download and install it on my laptop. Unlike in the past this service pack doesn’t add a lot of new features to the operating systems. It is more of a big security update. The release notes list almost 800 updates included. It includes all of the security updates that have previously been released via Windows Update. For Windows 7, this service pack does include client-side support for RemoteFX and Dynamic Memory which are 2 new virtualization features enabled in Windows Server 2008 R2 SP1. You can find out more about these features here.
