Windows 10 October 2020 Update is now live for the public. With this update, Microsoft has focused on performance improvements, feature updates, and the stability of the operating system, along with some small visual changes. After over a year of Insider testing of Windows 10 version 20H2, Microsoft is now offering the October 2020 Update to some of the users seeking it (or via the ISO files).

Those who are currently running Windows 10 version 2004 (the May 2020 Update) will have a much smoother and faster experience since for them the new feature update will install like a monthly update, similar to version 1909 from last year.
