Microsoft has published an update on the Release Preview channel for Insiders who are still on Windows 10 version 21H2. Although Microsoft also offers them to switch to the latest version 22H2, but they can opt to remain on the older version if they want to.
That said, Microsoft has now published KB5016688, installing which will upgrade your operating system’s build to 19044.1947 whilst keeping your OS version 21H2. This flight does not include any new features, but some fixes to improve your experience.
One of the major improvements is that Microsoft has added the ability for sysadmins to add and control the language-related features on remote computers using endpoint managers.
Let us see what other improvements and fixes have been introduced before learning how to install the update.

The exception code was 0xc0000409 (STATUS_STACK_BUFFER_OVERRUN).
- An issue that affects a lookup for a nonexistent security ID (SID) from the local domain using a read-only domain controller (RODC) has been addressed. The lookup unexpectedly returned the STATUS_TRUSTED_DOMAIN_FAILURE error instead of STATUS_NONE_MAPPED or STATUS_SOME_MAPPED.
