Retirement for the Semi-Annual Enterprise Channel for Unmanaged Devices on 6th April 2026

Starting in April 2026, Microsoft will retire the Semi-Annual Enterprise Channel installation option for unmanaged devices in the Microsoft 365 admin center. We are making this change to streamline installation choices and help organizations move toward more predictable, secure, and up-to-date release channels.

This retirement only affects the installation option for unmanaged devices. It does not change the update channel of any existing unmanaged device already assigned to the Semi-Annual Enterprise Channel.
