How to Change Default Language on Windows 10

Changing the default language on Windows 10 affects the display language for menus, settings, and apps, and it also sets the preferred language for typing and speech recognition. This guide walks you through adding a new language pack, setting it as the default, and adjusting related settings. You’ll need administrator access to your PC to complete the steps.

What You’ll Need

• A Windows 10 PC with administrator privileges.
• An internet connection to download language packs.
• Your Microsoft account password (if you use one) to confirm changes.

Step-by-Step

1. Open Settings. Click the Start button (Windows icon) in the bottom-left corner, then select the gear icon (Settings). Alternatively, press Windows + I.
2. Go to Time & Language. In the Settings window, click on Time & Language.
3. Select Language. In the left sidebar, click Language. You’ll see a list of currently installed languages under “Preferred languages.”
4. Add a language. Click the + Add a language button. A search box appears.
5. Search for your language. Type the name of the language you want (e.g., “Spanish”, “French”, “German”). A list of matching languages will appear. Select the one you want, then click Next.
6. Install the language pack. In the “Install language features” window, you’ll see options like “Set as my Windows display language” and “Speech recognition”. Make sure the checkbox for Set as my Windows display language is checked. You can also check other features like text-to-speech if needed. Click Install.
7. Wait for installation. Windows will download and install the language pack. This may take a few minutes depending on your internet speed.
8. Set as default (if not already). After installation, the new language appears in the list. If it’s not already set as the default, click on it, then click Set as default.
9. Sign out and sign back in. To apply the new display language, you need to sign out of your Windows account and then sign back in. Click the Start button, click your profile icon, and select Sign out. Then log back in.
10. Verify the change. After signing in, check the Start menu and Settings – they should now be in your chosen language.

Common Mistakes

• Not checking “Set as my Windows display language” during installation. If you miss this, the language will be added but not applied.
• Forgetting to sign out and back in. The display language change only takes effect after a sign-out/sign-in cycle. Restarting your PC also works.
• Choosing the wrong regional variant. For example, selecting “English (United Kingdom)” vs. “English (United States)” affects spelling and some terms. Make sure you pick the variant you want.
• Not having admin rights. If your user account is a standard account, you may be prompted for an administrator password. If you don’t have it, you can’t install language packs.

Tips

• Keyboard layout: If you also want to type in the new language, after adding the language, click it and choose Options. Then under “Keyboards”, click Add a keyboard and select the layout you need (e.g., AZERTY for French). You can switch between keyboards by pressing Windows + Space.
• Speech recognition: If you plan to use Cortana or dictation in the new language, make sure to install the speech recognition feature during the language pack installation (or later via Options).
• Handwriting: For touch devices, you can also install handwriting recognition for the new language.
• Keep the old language: You don’t need to remove the previous language. You can switch back anytime by changing the default again.

Troubleshooting

• The language pack won’t download. Check your internet connection. If you’re on a metered connection, Windows may block downloads. Go to Settings > Update & Security > Delivery Optimization and ensure it’s not restricted. Also, try pausing and resuming the download.
• The language appears in the list but the display doesn’t change. Make sure you signed out and back in. If you did, try restarting your PC. If it still doesn’t change, go to Settings > Time & Language > Language, click the language, and click Set as default again, then sign out/in.
• Some apps still show the old language. Some legacy apps may not fully support the new display language. They might have their own language settings. Check the app’s preferences or options for a language selector.
• You see “Language pack not supported” error. This can happen if your Windows 10 edition (e.g., Home vs. Pro) doesn’t support certain language packs. All editions support display language packs, but some features like speech may be limited. Try installing just the display language (uncheck other options).
• Can’t find the language in the list. Make sure you’re searching in the correct field. The search box in the “Add a language” window searches by language name, not by country. For example, search for “Chinese” not “China”.

Frequently Asked Questions

Will changing the display language affect my files and apps?

No, your files, documents, and installed apps remain unchanged. Only the Windows interface language changes. Apps that support the new language will switch automatically, but others may stay in their original language.

Can I have two languages and switch between them easily?

Yes, you can have multiple languages installed. To switch, go to Settings > Time & Language > Language, select the language you want, and click “Set as default”. Then sign out and back in. Alternatively, you can use the language bar in the taskbar (if enabled) to switch keyboard layouts, but that doesn’t change the display language.

Do I need to reinstall Windows to change the language?

No, you don’t need to reinstall. Installing a language pack and setting it as default is sufficient for most users. However, if you want to remove the original language entirely, you can do so after the new one is set, but some system components may still use the original language.

Why is the language pack taking so long to download?

Language packs can be large (several hundred MB). Download time depends on your internet speed and server load. You can check progress in Settings > Update & Security > Windows Update. If it’s stuck, try pausing and resuming.

Can I change the language for only one user account?

Yes, language settings are per-user. Each user account can have its own default display language. You’ll need to change it while logged into that account.

What if I want to go back to the original language?

Simply follow the same steps: add your original language (if not already in the list), set it as default, and sign out/in. You can then remove the other language if you no longer need it.
