OK. I hope everything will go well.

Hello Yuhao,

Update: KB5050081 (WIN 10 22H2), KB5050094 (WIN 11) fixes this issue, but it's preview only. Do you know how long it takes to become "standard" update? Would need this update also for WIN10 21H2.

Best regards,

Orderbob

The preview update eventually turns into a regular update based on what the dev team decides and the test results. It’s not something that Microsoft support or agents can predict. If you’re looking for that update, it’s a good idea to keep checking Windows Update regularly.

I don't know if this will help, but if you google the KB# for each of those updates and scroll to the bottom, there's a tab for "Catalog" that will take you to the Microsoft Update catalog downloads for each .msu file:

Windows 10 22H2 - (KB5050081, Details)

Windows 11 23H2 - (KB5050092, Details)

Windows 11 24H2 - (KB5050094, Details)

Oddly, not every KB article page has specific instructions on how to install the .msu update package if you download it from the Catalog link. The page for KB5050094 does, however, and I'll paste it here:
