Thanks for your posting on Q&A.
Please help to confirm how many ConfigMgr clients shown as required the Feature Update to Windows 10 Version 21H2 x64-based systems 2021-11 via Enablement Package (5003791) after installing the Feature update to Windows 10 (business editions), version 21H2, en-us x64 (3012973). Please try to review the
StateMessage.log on the clients and make sure the clients already sent the state messaging to the MP.
According to this link, Windows 10, versions 2004, 20H2, 21H1, and 21H2 share a common core operating system with an identical set of system files. So we could upgrade to Windows 10 21H2 after installing the Enablement Package (5003791).
By the way, what is the version of your MECM? I will research further on my lab environment and confirm whether it is a bug. I will come back as soon as possible if there are any updates.
Thanks for your understanding and cooperation.
