Wie gestern angekündigt hat Microsoft heute das erste Service-Pack (SP1) für sein Betriebssystem Windows 7 zum Download bereit gestellt.
Die 32-Bit Version ist dabei knapp 540 MB groß, die 64-Bit Version erstreckt sich auf über 900 MB. Die Versionsnummer des SP1 lautet 7601.17514.101119-1850.
Wie bereits gestern erläutert enthält das SP1 für Win7 keine wesentlichen Funktionserweiterungen laut Microsoft Informationen. Selbst die in den letzten Monaten oft genannte Out-of-the-Box Funktionalität für USB 3.0 wird in dem Dokument mit keinem Wort erwähnt. Demnach werden dem Anschein nach auch künftig Hersteller spezifische Treiber für die USB 3.0 Controller notwendig sein, die bis dato weder bei Intel, noch bei AMD den Weg in die Southbridge gefunden haben.
Neben den gesammelten Sicherheitsupdates ist allerdings der offizielle Support für die AVX SIMD-Einheit hervorzuheben, die mit den Intel Sandy Bridge Prozessoren eingeführt wurde und - sogar in einer erweiterten Form (FMA4) - bei den kommenden AMD Bulldozer-Prozessoren Verwendung finden soll, sowie die verbesserte Kompatibilität mit Datenträgern, die nativ 4 KB Sektoren zur Verwaltung verwenden. Zudem sollen im Audio-Bereich Anpassungen stattgefunden haben, indem die Leistung für die HDMI-Audiowiedergabe erhöht worden sein soll. Im Detail:
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 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. More information on these enhancements is detailed in Microsoft KB 982018.
Das SP1 kann auch über die integrierte Update-Funktion von Windows bezogen werden.
Nachtrag vom 23.02.2011 Anscheinend hat Microsoft auf einigen Mirrors versehentlich die alte RC-Version zum Download bereitgestellt statt der Final. Ob man die richtige Version erwischt hat, kann man anhand der Hashwerte prüfen, z.B. mit VisualHash. Die 32-Bit Version des SP1 muss einen SHA-1-Hash von "c3516bc5c9e69fee6d9ac4f981f5b95977a8a2fa" haben, die 64-Bit von "74865ef2562006e51d7f9333b4a8d45b7a749dab". Unterscheiden sich die Prüfsummen, den Download einfach nochmal anstoßen.
