The Windows 10 cumulative update released by Microsoft last month caused problems with the input method indicator and language bar, according to a message posted on the Microsoft Health Dashboard. The cumulative update number for the problem, KB5014666, was released on June 28, and subsequent updates, including the July B stable version update, also contain the same problem.
Microsoft writes: “After installing updates released on June 28, 2022 ( KB5014666) or later updates, the Input Indicator and Language Bar might not appear in the notification area. The notification area is normally located on the right end of the taskbar. Affected devices have more than one language installed. The Input Indicator and Language Bar is used to switch between input or keyboard languages on Windows devices and is used especially with languages that use Input Method Editors (IME).”
That is to say, as long as the user has installed the update after June 28, the problem will be encountered. At present, Microsoft has fixed the problem through KIR technology. The affected system versions include Windows 10 20H2~21H2 versions, and other versions and Windows 11 have not heard of similar situations for the time being.
