Microsoft has been very busy over the past month with Windows 11 24H2 updates. Earlier in August, we noticed the company released a new 24H2 Safe OS Dynamic Update. Microsoft said the update was for "improvements to the Windows recovery environment"

Yet another Windows 1124H2 update, under KB5041178, is available as well. This update "makes improvements to Windows setup binaries or any files that setup uses for feature updates in Windows 11, version 24H2" according to the company.

Microsoft also released a Windows 11 24H2 update, under KB5040529, a few weeks ago. This one had a number of new features, including Emoji 15.1 support, a new account manager for the Start menu, a way to "drag apps from the pinned section of the menu and pin them to the taskbar", a new way for Windows to back up a number of sound settings, new Lock screen content to view such as sports, traffic, and finance news, and quite a lot more.
