Windows 10 and future Windows versions With Windows 10, Microsoft declared it will update Windows at a faster cadence than before. There will not be an official "Windows 11"; instead, Windows Update (or another enterprise servicing model) will update the existing Windows 10 to a new version. At the time of writing, two such updates have occurred, in November 2015 (also known as version 1511, referring to the year and month of servicing) and July 2016 (version 1607, also known by the marketing name of Anniversary Update).
