After Updating Win10 the notice on the update page of Settings that Windows is enrolled in the ESU program disappears and you get a new warning that Win10 is EOL. Microsoft also adds a Big banner & Taskbar notification that comes just short of forcing you to upgrade to Win11 if the device meets the hardware requirements. The update to turn Win11 24H2 into 25H2 was not included on any of our hardware, and if you run it after October's updates there's a .NET update available for 25H2. October's update breaks localhost (127.0.0.1) HTTP/2 connections, which Microsoft has semi-fixed with Known Issue Rollback.
