Microsoft has started to release the latest version of its desktop operating system, the November 2019 Update or version 1909.

Windows 10 November 2019 Update is the first ever feature update that is being delivered as a cumulative update, similar to a monthly update to create minimal disruption, if any. Those upgrading from the May 2019 Update can simply install version 1909 like any monthly cumulative update. However, earlier versions will still have to go through the lengthy installation process.
