Windows 11 functionality interrupted due to certificate expiration

Early adopters of Windows 11 may not be able to use the screenshot tool, touch keyboard, or emoji panel unless they manually update the operating system. Microsoft released patches to fix most of the problems, Referencing an expired certificate As the reason.

The patch will be sent to the affected device as an automatic update, but you can manually install the preview patch, KB5006746If you want it immediately. It fixes the touch keyboard, voice input, emoji panel (Windows key + period, for those who have not played), and the Getting Started and Tips section in Windows 11. It does not repair the screenshot tool (however, Windows key + Shift + S). Microsoft recommends using the Print Screen key as an alternative method.
