Last updated: November 2018

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 update, upgrade or make other changes to your software. 

Windows 10


Home, Enterprise, Education, Pro, and Pro for Workstation editions 

Windows 10 Semi-Annual Channel (SAC) is governed by the Modern Lifecycle Policy (as of January 25, 2018). For more information, see the Microsoft Lifecycle Policy or review the Modern Lifecycle FAQ

Feature updates will be released twice a year for Windows 10 via the Semi-Annual Channel (SAC), targeting March and September annually. Updates are cumulative, with each update built upon those that preceded it; you should always install the latest feature update (version), before your current version reaches end of service, to remain supported by Microsoft thru monthly quality updates.
 
As of September 6, 2018, we have evolved our servicing timeline for customers who need more time to test and deploy Windows 10 Enterprise and Education feature updates. To that end, feature updates will be serviced with monthly quality updates as follows:
 
Edition  March* feature updates  September* feature updates
Windows 10 Enterprise
Windows 10 Education
Serviced for 18 months from release date Serviced for 30 months from release date
Windows 10 Pro
Windows 10 Pro for Workstation
Windows 10 Home
 
Serviced for 18 months from release date, however based on your setting, the latest feature update may be automatically installed on your device upon availability. Serviced for 18 months from release date, however based on your setting, the latest feature update may be automatically installed on your device upon availability.
* Feature updates will be released twice annual with a target of March and September.
 

Some editions1 can defer semi-annual feature updates at Settings  >Windows Update >Advanced options or via a policy that an organization's management system may provide to the device. On devices that haven't been configured for deferral, you'll need to install the latest feature update to help keep your device secure and have it remain supported by Microsoft. New versions may be automatically installed prior to the end-of-service date of the current version on your device.

1 Home edition does not support the deferral of feature updates and will therefore typically receive a new version of Windows 10 prior to the end-of-service date shown.
 

By Windows 10 version, below are the availability and end of service dates segmented by edition.

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 whether the software was acquired via Volume Licensing, OEM, or FPP. To learn more about these rights, review the downgrade rights licensing brief. 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 Microsoft Lifecycle Policy. A device may not be able to run prior versions of Windows if the device hardware is incompatible, lacks current drivers, or is otherwise outside of the original equipment manufacturer’s (OEM) support period.
