Microsoft has announced that it will release Service Pack 1 (SP1) Beta by the end of july,
At the Tech-Ed conference Microsoft said:-
SP1 will be a joint release for both Windows Server 2008 R2 and Windows 7. From the server side,we’ve included two key new features:
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.
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. It also enhances the end-user’s hardware experience with support for USB redirection. 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.
Microsoft has already said that SP 1 will not contain any kind of change or new features it will just include Updates and Hot Fixes.
