To fix this issue, delete the Preload registry folder and restart (or sign out) the computer:
This folder seems to be some legacy remnant that contains non-user-specified keyboard layouts to be added to the list of languages when the user signs in. While the fix itself works through restarts, there’s a few things that seem to bring back this folder
To automate the procedure create a txt file and paste the contents below.
Windows Registry Editor Version 5.00 [-HKEY_USERS\.DEFAULT\Keyboard Layout\Preload]
You can then save the file with .reg extension and run it if registry folder comes back. You need to logout or restart for changes to take effect.
Tip: From notepad use quotes like to “RemoveLang.reg” to save with new file extension.
