Windows lifecycle fact sheet





Last updated: January 2016

Every Windows product has a lifecycle. The lifecycle begins when a product is released and ends when it’s no longer supported. Knowing key dates in this lifecycle helps you make informed decisions about when to upgrade or make other changes to your software.

End of support

End of support refers to the date when Microsoft no longer provides automatic fixes, updates, or online technical assistance. This is the time to make sure you have the latest available update or service pack installed. Without Microsoft support, you will no longer receive security updates that can help protect your PC from harmful viruses, spyware, and other malicious software that can steal your personal information. For more information go to Microsoft Support Lifecycle.

 Client operating systems  Latest update or service pack  End of mainstream support  End of extended support
  Windows XP  Service Pack 3  April 14, 2009  April 8, 2014
  Windows Vista  Service Pack 2  April 10, 2012  April 11, 2017
  Windows 7*  Service Pack 1  January 13, 2015  January 14, 2020
  Windows 8  Windows 8.1  January 9, 2018  January 10, 2023
Windows 10, released in July 2015**  N/A  October 13, 2020  October 14, 2025

Prior versions of Windows, including Windows 7 and Windows 8.1, have limited support when running on new processors and chipsets from manufacturers like Intel, AMD, NVidia, and Qualcomm. For more information, please see the Support Lifecycle FAQ.

* Support for Windows 7 RTM without service packs ended on April 9, 2013. Be sure to install Windows 7 Service Pack 1 today to continue to receive support and updates.
** Updates are cumulative, with each update built upon all of the updates that preceded it. A device needs to install the latest update to remain supported. Updates may include new features, fixes (security and/or non-security), or a combination of both. Not all features in an update will work on all devices. A device may not be able to receive updates if the device hardware is incompatible, lacking current drivers, or otherwise outside of the Original Equipment Manufacturer’s (“OEM”) support period. Update availability may vary, for example by country, region, network connectivity, mobile operator (e.g., for cellular-capable devices), or hardware capabilities (including, e.g., free disk space).

Service packs and updates

Service packs and updates are part of the process of keeping Windows Vista, Windows 7, and Windows 8 up to date. Service packs combine the latest updates and fixes into one package or download. A service pack can include security and performance improvements as well as support for new types of hardware. To install the latest service pack for Windows Vista, or Windows 7, or to install the latest update for Windows 8, visit the Service Pack Center.

Windows downgrade rights

To use prior versions of Windows software on PCs installed with newer versions, it is possible for consumers to obtain a license for downgrade rights. These downgrade rights will vary depending on if the software was acquired via Volume Licensing, OEM, or FPP. To learn more about these rights, review the downgrade rights licensing brief.
