Remember, the Language bar will be displayed either on the taskbar or desktop, only when you select more than one language as input language. Be sure your second language is listed in the input language list. If not you can add it by pressing Add button to add another language. If you find that your Language Bar is still missing, here is what you may try.
Language Bar missing in Windows 11/10
In Windows 11, open Settings > Time & language > Advanced keyboard settings. Click on Language bar option and a new Test Services and Input Languages box will open. In Windows10, open Settings > Time and Language > Language settings. Click on Keyboard to open the following settings:
Now, for either Windows 11 or Windows 10, under the Switching Input Methods, you will see a checkbox for Use the desktop language bar when it’s available. Select it. Next click on Language bar options. In the Text Services and Input Languages box that opens, select the Language Bar tab.
Set your preferences here. Next, select the Advanced Key Settings tab.
You can change the language bar hotkeys or key sequence here. In Windows 7, open Registry Editor and navigate to the following key: Check for a string parameter named CTFMon. If it exists, ensure that its path is set to C:\Windows\system32\ctfmon.exe. If not, create this String Value. Restart your computer. Now click on the Language Bar icon that you will now on the taskbar and select Show the Language bar. To hide the Language bar, select Close the Language bar. You can also control the behavior of the Language bar via the Contol Panel > Region & Language > Keyboards & Languages tab > Change keyboards > Language bar tab. Hope the changes made in Windows 10/8 are clear.
