Service Pack Lifecycle Policy

View products that this article applies to.


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).

Service Pack Policy
  • When a new service pack is released, Microsoft provides either 12 or 24 months of support for the previous service pack, varying according to the product family (for example, Windows, Office, Servers, or Developer tools).
  • When support for a service pack ends, Microsoft no longer provides new security updates, DST updates, or other nonsecurity updates for that service pack. Commercially reasonable support will continue to be available, as described in the following.
  • When support for a product ends, support of all the service packs for that product also ends. The product’s lifecycle supersedes the service pack policy.
  • Support timelines for service packs remains consistent within the product family.
  • Microsoft publishes specific support timelines for a previous service pack when the new service pack is released. 
Customers are highly encouraged to stay on a fully supported service pack to ensure they are on the latest and most secure version of their product.
For customers on supported products with service pack versions that have left full support, Microsoft offers commercially reasonable support as follows: 
Commercially reasonable support incidents will be provided through Microsoft Customer Service and Support and Microsoft managed support offerings (such as Premier Support). If the support incident requires escalation to development for further guidance, requires a nonsecurity update, or requires a security update, customers will be asked to upgrade to a fully supported service pack.
Commercially reasonable support does not include an option to engage Microsoft product development resources; technical workarounds may be limited or not possible. 
A matrix of the Microsoft product families and the duration of service pack support for each product family is as follows: 
Product Family Duration of Service Pack Support
 Windows client and servers  24 Months
 Dynamics  24 Months
 Office  12 Months
 Servers  12 Months
 Developer tools  12 Months
 Consumer software, multimedia, and games  12 Months

Starting with SQL Server 2017, no Service Packs will be released. SQL Server follows the modern servicing model as described in

Microsoft recommends that you apply the latest Cumulative Update (or one released in the last one year) for the corresponding release. The support team might require you to apply a specific Cumulative Update that addresses a specific problem when troubleshooting an issue.

This support policy permits customers to receive existing nonsecurity updates or to request new nonsecurity updates for the fully supported service packs during the Mainstream Support phase.

Service packs are not automatically modified to include nonsecurity updates developed after the service pack’s initial release date. An older service pack can be modified to include nonsecurity 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 saving time and time zone updates are built for fully supported service packs only.

It is strongly recommended 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.
