If you work on an English version of Windows, but you get Korean as a working language, your input language is set to Korean by default, but sometimes Windows will change this setting automatically when you switch between apps, thus a different keyboard layout too.
This affects all Windows versions regardless, and consequently, all apps running under Windows – including Sign In and MS Office.
Why this happens is because the Input Language can be programmed to be maintained per app or per window through an API that changes the input locale to a different or defaults keyboard layout is enabled for the user.
Some apps like Office try to decipher the language you use when typing a document, email, or presentation and change the input language accordingly (including keyboard layout).
Check out some solutions below that you can use when Windows 10 switches keyboard language on its own.
How do I disable keyboard language switch in Windows 10?
- Preliminary fixes
- Set a different input method
- Make the keyboard layout as default
- Choose only one input language and keyboard layout
- Disable keyboard actions
- Use Registry Editor to disable the keyboard layout toggle hotkeys
- Change the region settings
- Change registry settings through policy or login script
1. Preliminary fixes
- Press CTRL+SHIFT to switch to another language.
- Change the default language to one of the others you get, and reboot your computer, then change it back to the language you want to use and reboot again.
- Remove all other languages so that you’re left with only the one you want Windows to load with – the system language. Open that language and check the input method, then you can remove the one you don’t want and keep what you want. The default language will not switch back when using certain programs, but you can switch between them without problems.
- Avoid clicking SHIFT+ALT while using your computer as this creates a hotkey and can cause the Windows 10 switches keyboard language on its own error.
- Watch the language questions carefully when you install Windows 10 initially.
2. Set a different input method
- Type control panel in the Search box and select the app from results.
- Select Clock, language and region.
- Click on Advanced settings.
- Under the Switching input methods section, put a checkmark for Let me set a different input method for each app windows.
- Click on Save and see if the problem persists.
3. Make the keyboard layout as default
- Click Start and select Settings.
- Choose Change PC settings.
- Click on Time and language, then select Region and Language.
- Select the language that you want to see Windows in.
- Click Set as primary. The Will be display language after next sign-in message will appear under the language.
- Click Set as primary to move the language to the top. If it can become your Windows display language, the Will be display language after next sign-in will appear under the language.
- Sign out and then sign back in.
Note: When you change your primary language, your keyboard layout may change. When signing back into Windows, use the right keyboard layout for entering your password. Otherwise, you might not sign in.
You can also change your keyboard layout on the sign-in screen by clicking the language abbreviation button.
Your keyboard freezes as soon as you sign-in? Don’t worry, we’ve got the right solution for you.
4. Choose only one input language and keyboard layout
- Click Start and choose Settings.
- Click Time and Language.
- Go to Region and Language and select Advanced Keyboard settings.
- Under Override for different input methods, select from the drop-down menu the language you want to use.
- Close the window.
5. Disable keyboard actions

By default, pressing CTRL+SHIFT or ALT+SHIFT will cycle through any keyboard layouts you may have mapped and it is possible to do this by mistake. If you keep pressing any of these combinations, you can go back to the correct setting.
