Microsoft late Tuesday released its second major update to Windows 10 for the year, the Windows 10 November 2019 Update (version 1909). This update beats conventions in that is "minor" in comparison to the Windows 10 May 2019 (1903) Update, in that Microsoft didn't change too many under-the-hood components, but updated the operating system's user-interface. For example, the operating system retains the older version's driver model.

The Actions Center received several UI updates such as the ability to add items to your agenda directly from the calendar, improved sorting of notifications, improved accessibility of the Start menu, and the ability to use third-party accessibility software from even the Lock screen. The only notable under-the-hood changes concern the scheduler. Windows 10 now gets the ability to address multiple "favored" cores in a multi-core processor. A favored core is a physically superior core that can sustain higher boost clocks for longer. Microsoft's change-log follows.
