This problem has occurred for a while and does not take much time to solve it. However, when you enter an email in Outlook these days, as long as everything is changed to the input method, there will be no response. If you turn off outlook countless times a day, you can't stand it and start to find a solution to this problem. (Of course, even if the icon is displayed, the Outlook problem may not be solved .)
The solution to this problem on the internet is almost all about how to set it. In fact, what I encountered was not a setup problem, because I set it correctly or cannot display it. Finally, the solution found after unremitting search is as follows:
In the Registry: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run, add the string value:Ctfmon, the data is set:C: \ windows \ system32 \ ctfmon.exe
Okay. The input method icon will automatically appear after the device is restarted. However, you can run c: \ windows \ system32 \ ctfmon.exe directly in cmd to display the icon immediately.
