Yes! finally the long anticipated update for Windows 7 and Windows Server 2008 R2 is being made available to MSDN and TechNet subscribers. Microsoft has already shipped the final build of Windows 7 SP1 to OEM partners.

The final build string is as: 7601.17514.101119-1850. Service Pack 1 for Windows 7 is nothing more than a cumulative update that includes minor optimizations, bug fixes and security updates only. For Windows Server 2008 R2, it brings two new features viz. Dynamic Memory and RemoteFX.

RemoteFX, a key feature of Remote Desktop Services lets IT administrators deliver a rich graphics experience to end-users through virtualized desktops. Using new protocol enhancements between Windows Server 2008 R2 and Windows 7, end users can now access virtual machines on a wide variety of target devices and still get a rich graphics experience with server-side graphics processing.

With Dynamic Memory, IT administrators are able to pool available memory on a physical host and then dynamically dole that memory out to virtual machines running on the host, based on current workload needs.
