How to change default system language on Windows 10
If you're using your device with the wrong language configuration, you don't need to reinstall Windows 10. You only need to change a few settings to set the correct system language.
Disabling language sync
When you use a Microsoft account on Windows 10, the language settings will sync across devices. In the case that you're planning to change the region and language settings for only one computer, you should disable the option to sync these settings before making any changes to prevent the new configuration from overwriting the settings on your other devices.
To disable language syncing on Windows 10, use these steps:
- Open Settings.
- Click on Accounts.
Click on Sync your settings.
Under the "Individual sync settings" section, turn off the "Language preferences" toggle switch.
Once you complete the steps, you can change the language settings without affecting the settings on other devices. Changing system language
To change the system language on Windows 10, close any running app, and then use these steps:
- Open Settings.
- Click on Time & Language.
- Click on Language.
- Under the "Preferred languages" section, click the Add a preferred language button.<
- Search for the language you want on Windows 10.
- Select the language package from the result.
- Click the Next button.

- Check the Install language pack option.
- Check or clear the additional language features as needed.
- Click the Install button
- Click the Yes, sign out now button.
- Sign back into the Windows 10 account.
After you complete the steps, the language will change across the entire Windows 10 experience. The new changes will be reflected in the Sign-in screen, Settings app, File Explorer, Desktop, apps, browser, and websites you visit. Also, depending on your new settings, Windows 10 may prompt you to review your privacy settings again.
Changing region settings
If you're changing the system language because you're located in a different region, you'll also need to update the region settings.
To change the local region settings on Windows 10, use these steps:
- Open Settings.
- Click on Time & Language.
- Click on Region.
- Use the "Country or region" drop-down menu to select your geographical location if different from your current settings.
- Under the "Regional format" section, use the drop-down menu to select the correct formats for dates and times if different from your region.
- Click on Language on the left pane.
- Under the "Related settings" section, in the right pane, click the Administrative language settings option.
- In the "Administrative" tab, click the Copy settings button.
- Under the "Copy your current settings to" section, check the Welcome screen and system accounts and New user accounts options.
- Click the OK button.
- Click the OK button again.
- Click the Restart now button.
Once you complete the steps, the device will display the correct region settings according to your physical location.
Remember that when changing the language settings, you may lose the ability to use Cortana, as the digital assistant is not supported in most regions. This should work toget rid of the polish language pack.
