Product Note: Windows 7 Service Pack 1 For Providers
Important note: this document is designed for Local Support Providers (LSPs). This page was last modified on Tuesday, 31-Jan-2012 14:21:29 EST.
Windows 7 Service Pack 1 (SP1) become available through Microsoft Update on February 22nd. SP1 is the first significant update to Microsoft's newest operating system.
Information Systems & Computing (ISC) initially will support Windows 7 Service Pack 1 for its clients, including off-campus students, only on new systems that ship with Windows 7 Service Pack 1 pre-installed. ISC strongly recommends that all other University users adopt a "wait and see" approach, continuing to use previous versions of Windows (including Windows 7 RTM, Windows Vista SP2, and Windows XP SP3) until the initial bugs in Windows 7 Service Pack 1 are identified and fixed.
When ISC recommends this upgrade, it will be for systems that have at least 1.0 GB of RAM (2.0 GB or more of RAM will yield a substantially better experience).
Provider note: a Service Pack 1 installation on a fully patched Lenovo ThinkPad T410s with Windows 7 Ultimate took 3.0 GB of temporary disk space, one reboot, and approximately 1 hour and 10 minutes to complete. This installation actually returned approximately 2.5 GB of disk space when it was complete.
Current Windows 7 Incompatibilities
Microsoft's Remote Server Administration Tools will not install (but do function) under Windows 7 Service Pack 1.
How to Get It
Windows 7 Service Pack 1 is available at the University in three different ways:
- For users who have Automatic Update installed and set to automatically download and install, Windows 7 Service Pack 1 become available on February 22, 2011. The timing for users to receive SP1 through Automatic Update depends on a number of factors, including the user's Internet usage, location, language, and level of Internet demand for SP1.
Provider note: providers who wish to prevent Automatic Update from installing Windows 7 Service Pack 1 may deploy the Windows Service Pack Blocker Tool Kit. This toolkit uses an executable to create a registry key that blocks downloading of SP1 (and other Microsoft operating system service packs) for twelve months.
- For users with Penn's Windows Automatic Update Service (WAUS) activated, WAUS will install Windows 7 Service Pack 1 after the end of the "wait and see" period, currently planned for a month after the February 22nd release.
- The full download of Windows 7 Service Pack 1 is available from Microsoft here.
What's New in Windows 7 Service Pack 1
Windows 7 Service Pack 1 does not add many new features to Windows 7. Like Windows Vista Service Pack 1; it is mostly a compatibility, reliability, and performance upgrade.
Windows 7 Service Pack 1 does have a few new features:
- Windows 7 Service Pack 1 adds support for Advanced Vector Extension (AVX). This technology helps optimize and enhance performance for applications that are floating point intensive.
- Windows 7 Service Pack 1 also will support communications with third-party federation services that support the WS-Federation passive profile protocol.
Provider note: overall impact on client systems should not be major. Changes will be minor usability fixes and other specific issue fixes.
