As originally communicated in Michael Kleef’s blog post, today Windows Server 2008 R2 with SP1 is available for download.  You can experience the  new virtualization capabilities - Dynamic Memory in Hyper-V and RemoteFX - by downloading the service pack from the Microsoft Download Center if you are currently a Windows Server 2008 R2 customer.  Alternatively you can visit the TechNet Evaluation Center for an evaluation copy of Windows Server 2008 R2 with SP1.
