Beyond the topic, was there really a need to post this in two separate threads?
On topic, perhaps, I don't know, a listing of changes would be a welcome addition beyond a quoted paragraph telling people to open windows update. Though in all honesty I'm on XP so this really does not effect me.
You don't HAVE to open windows update. You can use one of the links in the OP. Also, there are a lot of fixes...
http://www.istartedsomething.com/20071208/vista-sp1-changelog/ * Adds support for Direct3D® 10.1, an update to Direct3D 10 that extends the API to support new hardware features, enabling 3D application and game developers to make more complete and efficient use of the upcoming generations of graphics hardware.
* Adds support for exFAT, a new file system supporting larger overall capacity and larger files, which will be used in Flash memory storage and consumer devices.
* Adds support for creating a single DVD media that boots on PCs with either BIOS or EFI.
* Enhances support for high density drives by adding new icons and labels that will identify HD-DVD and Blu-ray Drives as high density drives.
* Enhances the MPEG-2 decoder to support content protection across a user accessible bus on Media Center systems configured with Digital Cable Tuner hardware. This also effectively enables higher levels of hardware decoder acceleration for commercial DVD playback on some hardware.
* SP1 addresses issues many of the most common causes of crashes and hangs in Windows Vista, as reported by Windows Error Reporting. These include issues relating to Windows Calendar, Windows Media Player, and a number of drivers included with Windows Vista.
* Improves reliability by preventing data-loss while ejecting NTFS-formatted removable-media.
* Improves wireless ad-hoc connection (computer-to-computer wireless connections) success rate
* Improves Windows Vista’s built-in file backup solution to include EFS encrypted files in the backup.
* Improves the speed of adding and extracting files to and from a compressed (zipped) folder.
* Significantly improves the speed of moving a directory with many files underneath.
* Improves performance over Windows Vista’s current performance across the following scenarios:
o 25% faster when copying files locally on the same disk on the same machine
o 45% faster when copying files from a remote non-Windows Vista system to a SP1 system
o 50% faster when copying files from a remote SP1 system to a local SP1 system
* Improves responsiveness when doing many kinds of file or media manipulations. For example, with Windows Vista today, copying files after deleting a different set of files can make the copy operation take longer than needed. In SP1, the file copy time is the same as if no files were initially deleted.
* Improves the time to read large images by approximately 50%.
etc, etc....
