Windows Server 2008 R2 SP1 Beta is available

This July 2010, Microsoft has finally released the Beta version of its Service Pack 1 for Windows 2008 R2. It appears that the main new features are Hyper-V oriented, as far as I could understand on Technet:

• Dynamic Memory – the new feature that allows Hyper-V to dynamically change the amount of memory assigned to a virtual machine at run time, to get higher consolidation ratios.
• RemoteFX – provides support for rich graphics (Silverlight, 3D, etc…) when using Hyper-V to host desktop virtual machines. A good explanatory video about RemoteFX is the one of Michael Kleef.
