Windows lifecycle fact sheet

Last updated: April 2014

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. Here are the rights and limits of the Windows lifecycle.

 

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 .

End of sales

End of sales refers to the date when a particular version of Windows is no longer shipped to retailers or Original Equipment Manufacturers (OEMs). Examples of OEMS are Dell and Toshiba—PC manufacturers who often preinstall Windows software. When a version of Windows reaches its end of sales date, it’s a good time to think about upgrading.

This table gives end of sales dates for specific Windows operating systems.

Service packs and updates

Service packs and updates are part of the process of keeping your Windows product 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 XP, 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.
