Microsoft announced today that Windows 10 is moving to a six-month upgrade cycle like the one used for Office 365 ProPlus.
This update schedule doesn't come as much of a surprise. Microsoft released the Windows 10 Anniversary Update in August 2016, and the Creators Update made its public debut on April 11, leaving a seven-month gap between the flagship upgrades. Now the company has confirmed that it plans to release two updates per year--one in September and one in March--and said the Creators Update's antecedent should arrive in September 2017.
