Windows life cycle Specification Last updated: April 2014

Every Windows product has a life cycle. The lifecycle is counted from the time the product is released and ends when it is no longer supported. Understanding the critical dates of your lifecycle can help you make informed decisions about software upgrades or other changes. Here are the rights and limitations regarding the Windows lifecycle.

End Support

End support refers to the date that Microsoft no longer provides automatic patches, updates, or online technical help. At this point, you should make sure that you have the latest updates or Service packs available. Without Microsoft support, you will no longer receive any security updates that can help your computer defend against harmful viruses, spyware, and other malicious software that may steal personal information. For more information, go to the Microsoft support life cycle.

Sales End

End of sale refers to the date when a specific version of Windows is no longer shipped to the retailer or original equipment manufacturer (OEM). OEMs typically refer to the computer manufacturer that preinstalled Windows software, such as Dell and Toshiba. When a version of Windows reaches its sales end date, it is a good time to consider the upgrade.
