Unexpected keyboard language changes disrupt typing accuracy and workflow in Windows 11, especially for users who regularly work in multiple languages or switch between applications. The issue often stems from system settings, keyboard shortcuts, or configuration mismatches between Windows and individual apps like Microsoft Word. Addressing these factors can stabilize your input language and prevent unwanted automatic switches.

Remove Unwanted Keyboard Layouts and Languages

Unnecessary keyboard layouts or languages in your Windows 11 settings often trigger automatic switching. Removing unused layouts and languages ensures that Windows only cycles through the options you actively use, reducing the likelihood of unintended changes.

Step 1: Open the Settings app by pressing Windows + I. In the left sidebar, select Time & Language, then choose Language & Region on the right.

Step 2: Under Preferred languages, review the list of installed languages. Click the three-dot menu next to any language you do not use and select Remove to delete it from your system.

Step 3: For languages you want to keep, click the three-dot menu, choose Language options, and under Keyboards, remove any unused keyboard layouts by clicking the Remove button next to each unwanted layout.

By limiting your system to just the languages and layouts you use, you prevent Windows from switching to unused configurations.

Disable Keyboard Shortcuts That Trigger Language Switching

Windows 11 includes built-in keyboard shortcuts, such as Alt + Shift or Windows + Space, that allow users to switch input languages quickly. Accidentally pressing these shortcuts can cause the keyboard language to change without warning. Disabling or customizing these shortcuts minimizes accidental switches.

Step 1: Open the Settings app and navigate to Time & Language > Typing > Advanced keyboard settings.

Step 2: Click Language bar options to open the Text Services and Input Languages window. Select the Advanced Key Settings tab.

Step 3: Under Hot keys for input languages, select each entry and click Change Key Sequence.

Step 4: In the dialog, select Not Assigned for both Switch Input Language and Switch Keyboard Layout, then click OK to confirm.

Step 5: Click OK again to close the window and apply the changes.

This adjustment prevents accidental keyboard language changes caused by shortcut key presses.

Turn Off Automatic Keyboard Layout Switching for Apps

Windows 11 can automatically switch keyboard layouts based on the language detected in each app window. Turning off this feature forces Windows to use your preferred input method system-wide, reducing unwanted changes when moving between programs.

Step 1: Open the Settings app and go to Time & Language > Typing > Advanced keyboard settings.

Step 2: Uncheck the box for Let me use a different input method for each app window.

This ensures Windows applies your chosen input method consistently across all applications, rather than switching based on app context.

Adjust Language Preferences in Microsoft Office Applications

Office applications like Word or Excel can override Windows language settings and add keyboard layouts for proofing or spell-checking. Removing unwanted languages from Office prevents these apps from introducing new keyboard layouts that Windows may then adopt system-wide.

Step 1: Open Microsoft Word or Excel and select Options.

Step 2: In the Options window, click Language in the left sidebar.

Step 3: Under Office authoring languages and proofing, select any language you do not use and click Remove.

Step 4: Click OK to save changes, then restart your Office application and your computer to apply the update.

This step stops Office from introducing additional keyboard layouts and aligns application behavior with your Windows preferences.

Update Keyboard Drivers

Outdated or incompatible keyboard drivers can interfere with input language settings, causing erratic behavior. Ensuring your drivers are current improves system stability and reduces the risk of unexpected language switching.

Step 1: Press Windows + X and select Device Manager from the menu.

Step 2: Expand the Keyboards category, right-click your keyboard device, and choose Update driver.

Step 3: In the update window, select Search automatically for drivers. Follow the prompts to install any available updates.

Restart your computer after updating drivers to ensure changes take effect.

Modify Registry Settings to Prevent Automatic Layout Addition

In rare cases, Windows may continue to add keyboard layouts automatically due to registry configurations. Modifying the registry can stop this behavior, but proceed with caution and back up your registry beforehand.

Step 1: Press Windows + R to open the Run dialog. Type regedit and press Enter to launch the Registry Editor.

Step 2: In the Registry Editor, navigate to:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

Step 3: Right-click in the right pane, select New > DWORD (32-bit) Value, and name it IgnoreRemoteKeyboardLayout.

Step 4: Double-click the new value, set its data to 1, and click OK.

Step 5: Close the Registry Editor and restart your computer for the change to take effect.

This registry edit tells Windows to ignore remote keyboard layouts, reducing automatic additions.

Run the Keyboard Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and fix common keyboard-related issues, including incorrect language settings or registry errors.

Step 1: Open the Settings app and select System > Troubleshoot > Other troubleshooters.

Step 2: Find the Keyboard troubleshooter in the list and click Run.

Step 3: Follow the on-screen instructions to complete the troubleshooting process.

The troubleshooter will attempt to identify and resolve issues that may be causing the keyboard language to switch unexpectedly.

Optimizing these settings and removing unnecessary layouts stabilizes your keyboard input, so you can type without unexpected language changes interrupting your work. If the problem persists after following these steps, consider checking for recent Windows updates or seeking additional help from Microsoft support.
