Sure, you can change the language on your Windows 10 account, but what about the entire PC? Here's how.
You computer has a default system-wide language set in Windows 10, but you don't have to be stuck with it if your needs are different. With Windows 10 you can set the language settings for single accounts through the Settings app, but what about setting it for all accounts, the Lock Screen, and everywhere else on your PC? For that you'll need the Control Panel.
In this Windows 10 guide, we'll walk you through the steps to properly change the default language across on your entire computer.
Before we dive into this guide, it's important to note that if you're using a Microsoft Account, this preference will sync across devices. If you only want to change settings on one particular computer, you should go to Settings > Accounts > Sync your settings and turn off the Language preferences option.
Under Languages, click Add a language.
Click the language you want to add, and select the specific variation if applicable.
Select the new language and click Options (and download any the language packs as necessary).
On Region & language, select the new language, and click Set as default.
Click the Advanced settings link in the left pane.
Click the "Apply language settings to the Welcome screen, system accounts, and new user accounts."
On the Administrative tab, under the "Welcome screen and new user accounts", click theCopy settings button.
You'll find this feature especially useful when you work on a mixed-language environment where you need to configure workstations with different preferences to accommodate users. In addition, this feature will help in those times when you happen to purchase a new computer that ships from another country with a different language, or even when you move to another region of the world and you want to change your PC preferences to match the local settings.
