Every Windows product has a lifecycle. The lifecycle begins when a product is released and ends when it's no longer supported or sold. 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 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.
