Windows 10 release information

Microsoft has updated its servicing model. The Semi-Annual Channel is a twice-per-year feature update release targeting March and September, and 18-month servicing timelines for each release. The Semi-Annual Channel replaces the Current Branch (CB) and Current Branch for Business (CBB) concepts starting July 2017 with Windows 10, version 1703. This page is designed to help you determine if your devices are up to date with the latest Windows 10 feature and quality updates and to plan deployment schedules.

With each Semi-Annual Channel release, we recommend beginning deployment right away to targeted devices and ramp up to full deployment at your discretion. This will enable you to gain access to new features, experiences, and integrated security as soon as possible. For more information, see the blog post and Quick guide to Windows as a service.
