How to Fix Right Shift + Alt Not Changing Language in Windows

Due to Windows updates that changed how keyboard languages are managed, the Right Shift + Alt shortcut often stops working.
You can easily fix this by remapping the keys using a simple Command Prompt tweak.

Step 1: Open CMD as Administrator

Open the Start menu and type cmd.
Right-click on Command Prompt and select Run as administrator.

Step 2: Run the Fix Command

Copy and paste the following command into the CMD window, then press Enter:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout" /v "Scancode Map" /t REG_BINARY /d 000000000000000002000000380038E000000000 /f

Note: To confirm the command worked, make sure you see this message in CMD:

The operation completed successfully.

Restart your computer to apply the changes.
