As part of the effort to continually improve Microsoft software, updates and fixes are created and released for recognized issues. Many of these fixes are regularly combined into a single package (called a service pack) that is made available for installation. Both the Mainstream Support and Extended Support phases for software require a product’s supported service pack be installed to continue to receive full support (including security and DST updates).
|Product Family||Duration of service pack support|
|Windows Client and Servers||24 Months|
|Developer Tools||12 Months|
|Consumer Software, Multimedia, and Games||12 Months|
This support policy permits customers to receive existing non-security updates or to request new non-security updates for the fully supported service packs during the Mainstream Support phase.
Service packs are not automatically modified to include non-security updates developed after the service pack’s initial release date. An older service pack can be modified to include non-security updates developed after the service pack has released. Contact Microsoft and request the modification.
Security updates released with bulletins from the Microsoft Security Response Center will be reviewed and built for the supported service packs only. Daylight Savings Time and Time Zone updates are built for fully supported service packs only.
Microsoft strongly recommends that customers evaluate and install current service packs in a timely manner to make sure that systems are up-to-date with the most recent security software.
This revised policy became effective on April 13, 2010.
