Paul Thurrott’s January 14, 2011, article “Sneak Peek: A Quick Look at Windows 7 Service Pack 1” confirms what Microsoft has been telling us all along — namely, no big or dramatic changes, additions, or upgrades to Windows 7 will be included in SP1, though that is most definitely NOT also true for Windows Server 2008 R2 (Thurrott uses the phrase “major functional changes” to describe what’s coming for the server side in SP1).
Here’s the short list of “minor changes” to Windows 7 he found in a bootlegged version of a near-complete version of the upcoming service pack:
- Updates to Remote Desktop Services: required to accommmodate server-side changes known as RemoteFX for Windows Server 2008 R2.
- Improved third-party federation services support: improvements to the MS Federation Gateway Service (which lets users employ Live ID credentials and authentication on third-party sites) to support the industry-standard WS-Federation passive requestor profile (should make Federation Services easier and more reliable to use).
- Better HDMI Audio: Bug-fix for the small number of users who experienced disruption in HDMI audio following a system reboot.
- XPS document tweaks: Bug-fix for issue in documents that include both portrait and landscape pages that did not format print output correctly.
- Hot-fix/bug-fix rollup: All Service Packs routinely incorporate all previously released and new hot fixes plus bug fixes to establish a new, consolidated baseline for OS runtime code. Windows 7 SP1 does this, too.
Thurrott also reports that SP1 installation took over 40 minutes on a quad core Core 2 Duo PC, and that the Windows 7 build ID changes from 7600 to 7601 once the process completes successfully. Though there’s been no hint of install issues with SP1 for Windows 7 from any sources I’ve followed so far, remember to make a complete image backup of your system before installing SP1, and be sure to have an alternate boot/restore tool at hand. That way, if something does go kerflooey, you can use the boot/restore tool to restore your image and come away not too much worse for the wear. It can be difficult to roll back from a service pack install, and if the install fails at any time prior to completion and clean-up your system may not be bootable or working. You’ve been warned!
