How to Change System Language in Windows

This guide walks you through changing the display language of Windows 10 or Windows 11. It covers installing a language pack, switching the display language, and adjusting regional formats. You’ll need an administrator account and a stable internet connection.

What You’ll Need

A Windows 10 or Windows 11 PC with administrator privileges.
Internet access to download language packs.
Your Microsoft account password (if you use one) to sign in after the change.

Step-by-Step

Open Settings. Press Windows + I on your keyboard, or click the Start button and then the gear icon.
Go to Time & Language. In Settings, click “Time & Language” (Windows 10) or “Time & Language” (Windows 11).
Select Language & Region. In the left sidebar (Windows 10) or the main pane (Windows 11), click “Language & Region”.
Add a Language. Under “Preferred languages”, click “Add a language”. A list of available languages will appear.
Choose the Language. Search for your desired language (e.g., “Spanish”, “French”, “German”). Click on it, then click “Next”.
Install Language Features. In the dialog that appears, leave the default options checked (usually “Set as my Windows display language” and “Language features”). Click “Install”. Windows will download the language pack. This may take a few minutes depending on your internet speed.
Set as Display Language. Once installed, the language appears in your “Preferred languages” list. Click the three-dot menu (or the language name) next to it and select “Move up” until it’s at the top. Then click the three-dot menu again and choose “Set as my display language”.
Sign Out and Back In. Windows will prompt you to sign out. Save any open work, then click “Sign out”. After signing back in, the new language will be applied to the entire system.
Verify the Change. Open Settings again and check that the language is correctly applied. If some text still appears in the old language, restart your PC once more.

Common Mistakes

Not moving the language to the top: The display language is the first one in the “Preferred languages” list. If you don’t move it up, Windows may keep using the old language.
Forgetting to sign out: The language change only takes effect after you sign out and back in. A simple restart might not be enough; you need to actually sign out of your user account.
Installing a language that isn’t fully supported: Some languages have limited localization. Check that the language pack is marked as “Windows display language” available. If not, the interface may remain partially in English.
Changing regional format instead of display language: The “Regional format” setting (under the same page) only changes date, time, and number formats, not the language of menus and dialog boxes.

Tips

Use the language bar for typing: After adding a language, you can switch between keyboard layouts by pressing Alt + Shift or Windows + Space. This is handy if you type in multiple languages.
Keep the old language for legacy apps: Some older programs may not support the new language and will still display in the original one. That’s normal.
Download language packs in advance: If you’re on a slow connection, you can download the language pack before switching, so the change is quicker.
For Windows 11, use the “Language pack” link: In Settings > Time & Language > Language & Region, you may see a “Language pack” link under the language list. Click it to install additional features like handwriting or speech recognition.

Troubleshooting

Language pack won’t download: Check your internet connection. If you’re on a metered connection, Windows may block downloads. Go to Settings > Network & Internet > Wi-Fi (or Ethernet) and ensure “Set as metered connection” is off. Also, make sure Windows Update is not paused.
Display language doesn’t change after signing back in: Try restarting your PC completely. If that fails, go back to Settings > Time & Language > Language & Region, and confirm the language is at the top of the list. Then click the three-dot menu and select “Set as my display language” again. Sign out and back in.
Some text remains in the old language: Certain built-in apps (like the Microsoft Store) may need to be updated to fully localize. Open the Microsoft Store and check for updates. Also, some legacy Control Panel items may not be fully translated.
You can’t see the “Add a language” button: This can happen if your Windows edition is single-language (e.g., Windows 10 Home Single Language). In that case, you can only change the display language by upgrading to a multi-language edition or reinstalling Windows with the desired language.
Accidentally removed the wrong language: If you removed your original language and now can’t understand the interface, follow the same steps but navigate by the icons: Settings (gear) > Time & Language (clock icon) > Language & Region. Add your original language and set it as display.

Frequently Asked Questions

Will changing the display language affect my files and apps?

No, it only changes the language of Windows interface elements. Your personal files, documents, and installed applications remain untouched (though some apps may follow the system language).

Can I have multiple display languages and switch easily?

Yes, you can add multiple languages and move them up or down in the preferred list. To switch, you can sign out and back in, or use a third-party tool. Windows doesn’t offer a quick toggle for display language without signing out.

Do I need to reinstall Windows to change the language?

No, for most editions, you can simply install a language pack. Only single-language editions require a reinstall or an upgrade.

What’s the difference between “Display language” and “Regional format”?

Display language changes the text in menus, settings, and dialog boxes. Regional format changes how dates, times, and numbers are displayed (e.g., mm/dd/yyyy vs. dd/mm/yyyy).

Will keyboard shortcuts change after switching languages?

No, the default keyboard shortcuts (like Ctrl+C, Ctrl+V) remain the same. However, the keyboard layout may change if you add a new language, which affects which characters appear when you press keys.

Can I change the language for only one user account?

Yes, language settings are per-user. Each user can set their own preferred display language in their own account.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
