Service Pack 1 for Windows 7 and Windows Server 2008 R2 includes previously released updates and will deliver a number of powerful new features for Windows Server 2008 R2 for virtualization and Virtual Desktop Infrastructure (VDI). New techniques in memory management with the addition of Dynamic Memory functionality, as well as the ability to deliver full-fidelity graphic experiences in remote and virtualized environments with Microsoft RemoteFX, enable organizations to realize the greatest possible potential from their infrastructure. The resulting increase in efficiency and functionality allows for accelerated server consolidation, a more powerful virtualized desktop infrastructure, and an increased return on technology investments.

The impact of SP1 on the Windows 7 client operating system is considered to be minimal. Included changes address minor usability issues in specific scenarios, as outlined in this page. This page describes some of the notable changes in Service Pack 1 for Windows 7 and Windows Server 2008 R2. Note that many of the updates listed are already publically available and have been released via the Microsoft Download Center or Windows Update.

Changes specific to Windows 7
Additional support for communication with third-party federation services
Additional support has been added to allow Windows 7 clients to effectively communicate with third-party identity federation services (those supporting the WS-Federation passive profile protocol). This change enhances platform interoperability, and improves the ability to communicate identity and authentication information between organizations.

Improved HDMI audio device performance
A small percentage of users have reported issues in which the connection between computers running Windows 7 and HDMI audio devices can be lost after system reboots. Updates have been incorporated into SP1 to ensure that connections between Windows 7 computers and HDMI audio devices are consistently maintained.

Corrected behavior when printing mixed-orientation XPS documents
Prior to the release of SP1, some customers have reported difficulty when printing mixed-orientation XPS documents (documents containing pages in both portrait and landscape orientation) using the XPS Viewer, resulting in all pages being printed entirely in either portrait or landscape mode. This issue has been addressed in SP1, allowing users to correctly print mixed-orientation documents using the XPS Viewer.

Changes specific to Windows Server 2008 R2
Dynamic Memory
Constraints on the allocation of physical memory represents one of the greatest challenges organizations face as they adopt new virtualization technology and consolidate their infrastructure. With Dynamic Memory, an enhancement to Hyper-V introduced in Windows Server 2008 R2 SP1, organizations can now make the most efficient use of available physical memory, allowing them to realize the greatest possible potential from their virtualization resources. Dynamic Memory allows for memory on a host machine to be pooled and dynamically distributed to virtual machines as necessary. Memory is dynamically added or removed based on current workloads, and is done so without service interruption.

Microsoft RemoteFX
Businesses are increasingly looking to leverage the efficiency and cost savings that can come from a virtualized desktop infrastructure. With the addition of Microsoft RemoteFX in Windows Server 2008 R2 SP1, a new set of remote user experience capabilities that enable a media-rich user environment for virtual desktops, session-based desktops and remote applications is introduced. Harnessing the power of virtualized graphics resources, RemoteFX can be deployed to a range of thick and thin client devices, enabling cost-effective, local-like access to graphics-intensive applications and a broad array of end user peripherals, improving productivity of remote users.

RemoteFX can function independently from specific graphics stacks and supports any screen content, including today’s most advanced applications and rich content (including Silverlight and Adobe Flash), ensuring that end users maintain a rich, local-like desktop experience even in a virtualized thin-client environment.

RemoteFX also adds mainstream USB device support to virtual desktop computing, including support for USB drives, cameras and PDAs connected to the client device. RemoteFX also provides a platform for hardware and software partners to enhance RemoteFX capabilities in a variety of possible host, client and network configurations.

To use RemoteFX, the virtualization server must be running Windows Server 2008 R2 with SP1, the virtual machine must be running Windows 7 Enterprise with SP1 or Windows 7 Ultimate with SP1, and the remote client computer must be running either Windows Server 2008 R2 with SP1 or Windows 7 with SP1. To connect to the virtual machine, the remote client computer requires an updated version of Remote Desktop Services (included in the service pack for all editions of Windows 7).

Enhancements to scalability and high availability when using DirectAccess
DirectAccess is a new feature in the Windows 7 and Windows Server 2008 R2 operating systems that gives users the experience of being seamlessly connected to their corporate network any time they have Internet access. In Windows Server 2008 R2 SP1, improvements have been made to enhance scalability and high availability when using DirectAccess, through the addition of support for 6to4 and ISATAP addresses when using DirectAccess in conjunction with Network Load Balancing (NLB).

Support for Managed Service Accounts (MSAs) in secure branch office scenarios
SP1 enables enhanced support for managed service accounts (MSAs) to be used on domain-member services located in perimeter networks (also known as DMZs or extranets).

Support for increased volume of authentication traffic on domain controllers connected to high-latency networks
As a greater volume of IT infrastructure migrates to cloud-based services, there is a need for higher thresholds of authentication traffic to domain controllers located on high-latency networks (such as the public Internet). SP1 allows for more granular control of the maximum number of possible concurrent connections to a domain controller, enabling a greater degree of performance tuning for service providers.

Enhancements to Failover Clustering with Storage
SP1 enables enhanced support for how Failover Clustering works with storage that is not visible for all cluster nodes. In SP1, improvements have been made to the Cluster Validation and multiple Failover Cluster Manager wizards to allow workloads to use disks that are shared between a subset of cluster nodes.

Changes common to both client and server platforms
Change to behavior of “Restore previous folders at logon” functionality
SP1 changes the behavior of the “Restore previous folders at logon” function available in the Folder Options Explorer dialog. Prior to SP1, previous folders would be restored in a cascaded position based on the location of the most recently active folder. That behavior changes in SP1 so that all folders are restored to their previous positions.

Enhanced support for additional identities in RRAS and IPsec
Support for additional identification types has been added to the Identification field in the IKEv2 authentication protocol. This allows for a variety of additional forms of identification (such as E-mail ID or Certificate Subject) to be used when performing authentication using the IKEv2 protocol.

Support for Advanced Vector Extensions (AVX)
There has always been a growing need for ever more computing power and as usage models change, processors instruction set architectures evolve to support these growing demands. Advanced Vector Extensions (AVX) is a 256 bit instruction set extension for processors. AVX is designed to allow for improved performance for applications that are floating point intensive. Support for AVX is a part of SP1 to allow applications to fully utilize the new instruction set and register extensions.

Improved Support for Advanced Format (512e) Storage Devices
SP1 introduces a number of key enhancements to improve support of recently introduced storage devices with a 4KB physical sector size (commonly referred to as "Advanced Format"). These enhancements include functionality fixes, improved performance, and updated storage drivers which provide applications the ability to retrieve information as to the physical sector size of storage device.

796 Hotfixes and Security Updates
Windows 7 and Windows Server 2008 R2 Service Pack 1 includes all previously released updates for Windows 7 and Windows Server 2008 R2. Many of these updates are available to the public on the Microsoft Download Center and Windows Update, while others are only available to specific customers or partners. It is standard practice to include all of these updates in a Service Pack.

Microsoft RemoteFX
This is Not Needed .. In most cases users don't "NEED" to be able to go to youtube or othe media rich sites at their terminals. Totally unbelievable. If your users need that then buy them cheapo $300 Dells without an os and serv them an iscsi disk to boot off of and let them do the rendering/etc... on their end. Why tak up the resources of a server with "Kid Gets Hit In Head With Ball"? How much more in server infrastructure will you spend when all 300 of your users want to watch that video at the same time? It's mostly a bad idea...

Looks good, but if you've tried the beta, you may have noticed share and storage management is quite buggy atm. It crashes a lot.

I've had problems with the provision share feature, which just shows the server name in browse and no folders or nothing, making it effectively useless. Of course, advanced sharing is still there. On top of that, there seem to be issues with offering shares to Windows 2k/xp/2k3 clients.

Ultimately, I had to remove the beta tenatively. We're in the process here of eliminating older Windows OS, and I didn't notice any file sharing problems with Vista, 7, Server 2k8, & R2. On older versions, no matter what I did with the firewall, share settings, registry, etc., the shares were invisible.

Keep in mind this is a Beta release. I'll be putting it back when our upgrade is done, as Server 2k8 R2 runs dramatically smoother with SP1.

How about supporting multiple playback devices at all. XP could push audio through multiple devices simultaneously. Vista and 7 are DOA when it comes to doing so.

Unfortunately, playing audio to multiple interfaces at once is prohibited by W7 & Vista's new audio architecture UAA. It's of course a matter of Copy protection and can be circumvented by a clever program called "Virtual Audio Cable", which creates a virtual audio interface and lets you route audio wherever you like.
