Install MUI Language Packs on Windows 10: 2 Ways to do it

MUI (Multilingual User Interface) packages are language packs for Windows. These packs enable you to add new display languages to the Windows OS for alternative users.

Then multiple users can select alternative display languages if required, and any Windows version can host software in any other language. This is how you can download and install MUI packs for Windows 10.

How can I install MUI packs on Windows 10?

1. Using the Settings app

1. Enter region into the Cortana search box and press Enter to open the Region and language settings.
2. Now you can add new MUI language packs to Windows by clicking the Add a language button. 
   
3. Now choose an MUI pack to install from there.
4. The MUI pack will now be listed in the Region & language settings. Click the pack and then press its Options button.
   
5. Press the Download button under the Download language pack to download and install the pack.
   
6. When it’s installed, you can select the MUI pack listed on Region & language settings and click the Set as default button.
7. Restart Windows 10 to apply the new setting to the user account.

2. Using the install or uninstall Display Languages Wizard

Another option will be to download and install the language pack of your choice from third-party websites. This can sometimes provide you with rare language options that might not be available when you use the option above.

However, you must create a restore point before installing the language. This will help you restore your PC if anything goes wrong. You may encounter errors such as MUI_NO_VALID_SYSTEM_LANGUAGE.

So those are two ways to download and install an MUI pack in Windows 10. Note that Windows Store apps might not change to the new language settings until updated.
