Windows 10 release information
Feature updates for Windows 10 are released twice a year, around March and September, via the Semi-Annual Channel. They will be serviced with monthly quality updates for 18 or 30 months from the date of the release, depending on the lifecycle policy.
We recommend that you begin deployment of each Semi-Annual Channel release immediately as a targeted deployment to devices selected for early adoption 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 information about servicing timelines, see the Windows lifecycle fact sheet.
