Microsoft has already inadvertently confirmed that the recent Insider builds for Windows 11 are basically just test runs for the next major feature update for Windows 11, version 22H2, codenamed Sun Valley 2. This happened when the company published a page regarding the new Settings menu but quickly removed it as it probably realized it had given away the "SV2" reference, which is basically short for Sun Valley 2.
Earlier, leaked script had suggested that the Windows 11 22H2 "feature completion" and "config completion" deadlines were set for 4th February and 4th March respectively and so it was expected that soon after, Insiders builds would start servicing the new features.
And in terms of when Windows 11 22H2 (SV2) finally becomes generally available, a new report from German outlet Deskmodder alleges that Windows 11 22H2 will become GA starting in mid-September but a more gradual rollout will reportedly already commence in August for A/B testing before the final GA the next month.
The rumor isn"t entirely new though as an Insider "JimWynne" on a thread in the official Microsoft forum has also alleged that the same thing. Meanwhile, another Insider "RAJU.MSC.MATHEMATICS" says it is much later in November.
However, just because they are on the Microsoft forum doesn"t make their claims any more credible than the average Joe and therefore it is advised to take these rumors with a pinch of salt. The original Windows 11 21H2 came out in October last year so it is also possible that Microsoft releases 22H2 too, in October 2022 instead.
What we do know is that the Redmond giant is already working on the subsequent feature update for Windows 11, version 23H2 (Sun Valley 3), given away once again by Microsoft itself when it left a glaring clue during a live stream. And it also means Windows 11 22H2 is probably not too far away.
