Microsoft today released the new Windows 11 Build 22621.105 (KB5014688) to Insiders on the Release Preview channel. This update for Windows 11 22H2 Insider build 22621 was made available to Insiders last week.
However, it looks like Microsoft forgot to add the release notes for the new build 22621.105 (KB5014688). Clicking on the “Details” option next to an update in the settings opens a blank page where the changelog for the new build should be placed. Here is the support web page for build 22621.105, which Microsoft will probably update soon. Hence, it’s not confirmed what’s new in the build at the moment.
