While most Windows service packs are hardly worth discussing, Windows Vista Service Pack 1 (SP1) has been steeped in mystery almost since before Vista itself was completed. With Vista, Microsoft has engineered a new update deployment technology that allows administrators and power users to "slipstream" service packs and other fixes into new Vista installations in a manner that is much simpler than with previous Windows versions. But the real issue with SP1 is in how Microsoft is handling--or mishandling, in my opinion--the dissemination of information about this release. For this reason, and because there are so many silly rumors floating around, I've created a FAQ for Vista SP1 that will be updated as new information is released. My guess is that these updates will be unnecessarily frequent.
Q: What is Windows Vista Service Pack 1 (SP1)?
A: Previously codenamed Fiji, Windows Vista SP1 is the first major update to Windows Vista, a collection of bug fixes, functional changes, and other additions to Microsoft's latest operating system. As is the case with Vista, however, the feature set for SP1 has changed dramatically over time. Originally, Microsoft hoped to ship a Media Center update with SP1 but my understanding is that this update will no longer be included in SP1.
