想明白了……23H2包括SV2M4的更新内容，SV2M4将带来一些23H2的新功能，如Copilot on Windows。
Microsoft then went on to announce the next big Windows 11 update, which, up until now, was being tested as the Windows 11 23H2 release. However, Microsoft didn’t announce Windows 11 23H2 during the event. Instead, it announced another moment update coming to Windows 11 version 22H2, which just so happens to include most (if not all) of the 23H2 features.
而这几个StagingID就是为22H2带来SV2M4的功能启用，相较于SV2M4的Beta通道启用包以及23H2的启用包来讲，本次推送的更新缺少了一些内容。
Hello Windows Insiders, today we’re releasing Windows 11 Build 22621.2361 (KB5030310) to Insiders in the Release Preview Channel on Windows 11, version 22H2. We’re also beginning to roll out some of the new features announced yesterday by Yusuf, including Copilot in Windows (in preview)*, Modernized File Explorer, new text authoring experiences to voice access and new natural voices in Narrator, and Windows Backup. A more complete list of features will be shared next week on Sept. 26th.
Windows Central表示，微软这么做的原因是……
I have asked some sources about this, and it looks like Microsoft has decided to ship many of 23H2’s new features as part of a 22H2 moment update instead. The reason for this? Moment updates are not optional. The annual XXH2 release is always optional, so you don’t have to install it as an end-user if you don’t want to.
