Feature Update: Windows 10 version 1909
A feature update to Windows 10 version 1909 will be deployed to all managed desktops, starting in October 2020. This update will take around an hour and will require a restart. Devices that haven't been updated by 30/11/2020 will start the installation automatically.
Windows updates are essential to desktop security, can fix functional or reliability problems, and maintain compatibility with other systems. You will be prompted when updates are available, and can configure "active hours" during which your PC will not restart to complete update installation.
Most updates will install in the background with very little impact on performance.
Feature updates are more significant and can take about an hour to install, will impact performance, and require one or more restarts to complete.
