Today, Microsoft is announcing Service Pack 1 (SP1) for Windows Server 2008 R2 and Windows 7. Detailed information regarding SP1 will be released over the next several months; but today Windows Server 2008 R2 is announcing that SP1 will deliver two important new features that directly affect Microsoft’s desktop virtualization stack: Dynamic Memory and RemoteFX.
Dynamic memory is an enhancement to Hyper-V in R2 and allows IT administrators to pool all the memory available on a physical host and dynamically distribute it to virtual machines running on that host as necessary. That means based on changes in workload, your VMs will be able to receive new memory allocations without a service interruption. For a deeper look at Dynamic Memory check here.
RemoteFX is the latest addition to Microsoft’s desktop virtualization stack. Using this new feature in Windows Server 2008 R2, you’ll be able to deliver an even richer and more user-transparent desktop virtualization experience. RemoteFX functions independently of any graphics stack and supports any screen content, including rich content like Silverlight or Flash. Because it uses virtualized graphics resources, RemoteFX works on a wide array of target devices, which means you can deploy it over both thick and thin client hosts and a wide variety of network configurations.

"What Windows 7 SP1 will likely do
Yet speculate we must. Beyond the obvious bug fixes and security patches, we'll no doubt see support for the new USB 3.0 standard. Likewise, enhancements to the Bluetooth and Wi-Fi stacks will be slipstreamed in, allowing Windows 7 to retain its mantle as the most easily configured version ever.
But perhaps the most significant "update" to come out of Service Pack 1 will be the fact that it exists at all, and that by delivering it to market Microsoft will be signaling that it is now OK for IT shops to pull the trigger on their Windows 7 deployments. So here's to an early SP1 release -- and a final dismissal of that pesky rule of thumb." by infoworld.com
