Notable changes in Windows 7 SP1 and Server 2008 R2 SP1 on both Client and Server Platform

Notable changes in Windows 7 SP1 and Server 2008 R2 SP1 on both Client and Server Platform

SP1 includes all previously released updates for Windows Server 2008 R2 and Windows 7 which contains the update patches for certain components of operating System. Service Pack 1 for Windows 7 and Windows Server 2008 R2 represents Microsoft’s continuing commitment to quality. While many of the updates contained in SP1 are available as individual downloads, the integration of these updates in SP1 enhances the ease of deployment for IT administrators. This functionality coupled with advanced new virtualization features such as Dynamic Memory and RemoteFX, demonstrates how SP1 continues to provide ongoing improvements that organizations have grown to expect from Microsoft.

Changes Specific to Windows 7 SP1

  • 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 a computer running Windows 7 an HDMI audio device is lost after a system reboot. 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 SP1

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).

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.

Changes Common to both Client and Server Platform

  • More efficient power consumption

SP1 introduces functionality that enables user-mode use of the invariant Time Stamp Counter (TSC). When utilized by application workloads such as SQL Server, the invariant-TSC provides a high resolution multimedia timer (necessary for functionality such as OLTP, data warehouse processing, and so on) at far greater power efficiency than previously available alternatives.

  • 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. SP1 changes that behavior so that all folders are restored to their previous position.

  • 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.
