Microsoft have confirmed that the next feature update to Windows 10 will be September 2017. Microsoft have committed to a “twice-per-year feature release schedule, targeting September and March of each year”. This is close to the scheduling of last year’s anniversary update (August 2016) and the just released Creators Update (April 2017).
It’s good to have a predictable schedule for Windows 10 releases, it helps business in planning update rollouts but it does take a bit of the fun out of speculating when the next release will be.
