====== Prevent Windows 10 from adding EN_US keyboard ======
Windows 10 will add EN_US keyboard from time to time, even if you uninstalled it.
Solution:
  - Create a **DWORD** key named **IgnoreRemoteKeyboardLayout** inside **HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout** and give it a value of **1** (decimal).
  - Uninstall the undesired keyboard
  - Reboot

<code powershell Remove legacy reg key>reg delete "HKEY_USERS\.DEFAULT\Keyboard Layout\Preload" /f</code>
Or modify the Preload list with these codes: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-language-pack-default-values?view=windows-11
