Windows lifecycle fact sheetLast updated: August 2015In this page
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
