Surprisingly, Microsoft has decided that it will not be mandatory for OEMs to implement Service Pack 2 for Windows Vista and Windows Server 2008. In their most recent update (Jan. 19, 2009), they announced that the standalone and integrated builds for both Windows Vista SP2 and Windows Server 2008 R2 are optional.



What does that mean for OEMs and us, the customers? Basically, it means that OEMs will not be compelled to ship their systems with the new builds, which would have required extensive work (tests, implementation, logistics). They are also not required to send their customers the Service Pack 2 upgrades.



Microsoft's decision to make this update optional is likely due to the impending release of Windows 7. Many OEMs are probably hesitant about spending more money and effort into qualifying the new builds with their products, especially in light of the current economic situation. So, the onus will be on the consumer to update their Windows Vista or Windows Server 2008 installations via Windows Update.
