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:

  1. Create a DWORD key named IgnoreRemoteKeyboardLayout inside HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout and give it a value of 1 (decimal).
  2. Uninstall the undesired keyboard
  3. Reboot
Remove legacy reg key
reg delete "HKEY_USERS\.DEFAULT\Keyboard Layout\Preload" /f
