Six days ago, Service Pack 1 for Windows 7 and Windows Server 2008 R2 became available for MSDN/TechNet subscribers, and later today we'll all be able to get our hands on it.
As we reported last week, SP1 only contains two major new features, which will not affect the majority of users. The first of the two is RemoteFX, a standalone product that requires Windows Server 2008 R2 to be used. RemoteFX allows users to watch high-quality video and interact with 3D applications over a remote desktop session -- this will change the way Virtual Machines are used, as they have had limited display capabilities until now.
The second feature is an update for HyperV in Windows Server 2008 R2 called "Dynamic Memory". The feature is as simple as it sounds -- it dynamically allocates memory to virtual machines as required and is able to remove memory from virtual machines when others need higher resources. You can read more about the new features over on the Windows Server Team Blog.
The service pack will be pushed out through Microsoft/Windows Update, and will be made available as a stand-alone download.
Stay tuned for the announcement later today!
