Users who still have Windows 10 may have recently experienced a bug that sometimes caused the taskbar to disappear. In the worst case, the system could even hang and become unresponsive. This occurred on versions 20H2, 21H1, 21H2 and 22H2. Microsoft has implemented the necessary fixes and removed the faulty code. Thanks to the Known Issue Rollback feature, no update is required, but the bug fix is automatically applied to affected devices within 24 hours.
