Starting with update KB4497934, we are introducing functionality that allows you to decide when to install a feature update. You control when you get a feature update while simultaneously keeping your devices up to date. Feature updates that are available for eligible devices will appear in a separate module on the Windows Update page (Settings> Update & Security >Windows Update). If you would like to get an available update right away, selectDownload and install now. To find out more about this feature, please go to this blog. When Windows 10 devices are at, or within several months of reaching, end of service, Windows Update will begin to automatically initiate a feature update. This keeps those devices supported and receiving the monthly updates that are critical to device security and ecosystem health.
Notes:
This update includes quality improvements. Key changes include:
