Desktop Language Bar is a bar, either docked in the Taskbar or floating on the Desktop, that provides you an easy way to switch inputting languages from one to another. It seems defaulted to be docked in the Taskbar when you have more than one input languages selected in your Windows 10 system.
If you are using keyboard shortcuts to switch between languages, you probably don’t need to see this bar on your desktop anywhere. And here is how you can either disable it or hide it from your Desktop in Windows.
The setting is still buried in Control Panel and hasn’t been ported over to the Settings app. The easiest way to get access to it is through the Desktop Language Bar directly.
Right-click the Language Bar and choose Settings.
Then click Advanced settings link from Control Panel’s Language page.
You can uncheck the option “Use the desktop language bar when it’s available” and click Save to save the change.
You can also leave the option checked and go to Options to set the language bar in hidden mode as well.
Click OK to save the change, and that’s about it.
To enable or unhide the language bar to show it on your desktop, undo the changes we just described above.
