Microsoft has uploaded Windows 7 SP1 as well as Windows Server 2008 R2 SP1, you can download these updates over here.
Windows 7 and Windows Server 2008 R2 SP1 helps keep your PCs and servers on the latest support level. It also provides ongoing improvements to the Windows Operating System (OS), by including previous updates delivered over Windows Update as well as continuing incremental updates to the Windows 7 and Windows Server 2008 R2 platforms based on customer and partner feedback. This enables organizations to deploy a single set of updates.
This Service Pack is a collection of security updates but offers no new features for regular desktop users. Windows Server users on the other hand will receive two new features: RemoteFX and a Dynamic Memory feature for Hyper V:
Our first new feature, Dynamic Memory, takes Windows Server’s Hyper-V feature to a whole new level. Dynamic Memory lets you increase virtual machine density with the resources you already have—without sacrificing performance or scalability. In our lab testing, with Windows 7 SP1 as the guest operating system in a Virtual Desktop Infrastructure (VDI) scenario, we have seen a 40% increase in density from Windows Server 2008 R2 RTM to SP1. We achieved this increase simply by enabling Dynamic Memory.
This increased density does not come at the expense of security, as is the case with other offerings in the industry. Dynamic Memory preserves Windows 7 security without compromising density. My colleague Jeff Woolsey goes into detail in a recent post on this topic at the virtualization blog.
In addition, you get immediate benefit from the moment you turn on the virtual machine. There’s no waiting for memory management algorithms to work. Nor do you have to tweak the hypervisor with custom settings for specific workloads to maximize density. It’s an awesome out-of-box experience for all your virtualization workloads.
The second new feature, RemoteFX, is a first-to-market technology that we have demonstrated at multiple events. In fact, I was honored to be the first to show it publically at the Desktop Virtualization Hour last March.
RemoteFX is an exciting technology that lets you virtualize the Graphical Processing Unit (GPU) on the server side and deliver next-generation rich media and 3D user experiences for VDI. RemoteFX is also enabling new low cost ultra-thin client devices to enter the market. Together, these technologies will drive down the end-point cost and reduce endpoint power consumption to as little as a few watts.
Customers have already been successful with Dynamic Memory and RemoteFX, in early adopter deployments. Case studies, like the one we partnered with Sporton International on, show how using both RemoteFX and Dynamic Memory delivers real business value.
