Windows 10 April 2018 Update approaching end of service
For Windows 10 devices that are at, or within several months of reaching, end of service, Windows Update will automatically initiate a feature update; keeping those devices supported and receiving the monthly updates that are critical to device security and ecosystem health. The Windows 10 April 2018 Update (Windows 10, version 1803) will reach end of service on November 12, 2019 for Home and Pro editions. Starting this June, we will begin updating devices running the April 2018 Update, and earlier versions of Windows 10, to ensure we can continue to service these devices and provide the latest updates, security updates and improvements. We are starting this machine learning (ML)-based rollout process several months in advance of the end of service date to provide adequate time for a smooth update process.
