The language that you use on your Windows 10 computer can be changed in the Settings menu. To get started, open the Start menu and select Settings.
Once you are in the Settings menu, select Time & Language. From there, select Region & Language on the left-hand side. You will see a list of languages currently installed on your computer. If the one you want to use isn’t listed, click Add a language to add it to the list.
Once you’ve selected the language that you want to use, scroll down and click on the link that says Options. In the Options screen, you should see a dropdown list at the top that says Download and install language pack. Select your preferred language from the dropdown list and click the Install button.
Windows will now begin downloading and installing the language pack that you selected. Once the installation is complete, your preferred language will be the system language for Windows 10.
To change the language for individual applications and programs, you will need to open the application and look for language settings or other similar options. Each application uses its own set of language settings, so you may need to go through them individually to change the language.
If you ever need to switch back to the original language of Windows 10, simply repeat the steps above and select the language you originally had installed. That language will then become the system language of your computer again.
