Microsoft has unleashed the first public betas of Service Pack 1 (SP1) for both Windows 7 and Windows Server 2008 R2. Unlike some previous Microsoft service packs, these add little in the way of new capabilities, but there are still some compelling features that IT administrators should be aware of.

A message on the Windows Server Division WebLog announces "We managed to get this puppy out the door a few weeks early, so take advantage and download the code to evaluate the new features and benefits that SP1 can provide for server and desktop installations. The final version of SP1 is due out in the first half of next year."

The two biggest features of the SP1 beta are Dynamic Memory and RemoteFX. Dynamic Memory enables IT administrators to pool the physical memory on a server and dynamically allocate the memory to virtual machines running on that host based on the current workloads.
