Windows 10 Version Information
Microsoft has updated its service model. The six-year channel releases two feature updates per year, about March and September, with a service timeline of 18 months per version. Beginning with Windows 10, version 1703, the half-year channel replaces the current Branch (CB) and current Branch for business (CBB) concepts, which were released on July 27, 2017 for wide deployment. You should start by this date to anticipate the Windows update latency policy for your enterprise, based on broad deployment readiness.
With the release of each half-yearly channel, we recommend that you deploy to the target device immediately and elevate to full deployment as you decide. This way, you can get new features, experiences, and integrated security as quickly as possible. For more information, see the blog post and Windows as a service quick guide.
