Fortunately for people, in the fall of 2024, the long-term construction project from MS - W11 LTSC - finally appeared.
By the way, an interesting thing - modern versions of OS become obsolete, not when Microsoft says that it is all over, but when browser makers (the last of them) stop supporting this system and changes in the sites code are so great that the latest versions of browsers for this OS version can no longer cope with their tasks. Because for ordinary people, this support is key. As long as all sites work fine - they don't care about new versions of OS, only if there is something that will definitely force them to make some movements...
This is conveniently able to bypass "long-term formal support". For example, W10 1809 LTSC formally has support until 2029. But if it has, then who will develop browsers for this version until 2029? But no. Browser makers will intentionally stop supporting it from 2026 for all versions W10, although they formally must support W10 1809 LTSC up to 2029 year... Moreover, this will be the first experience in history with such a throw, since before W10 did not exist a LTSC (LTSB) channel.
