Change language Microsoft Mahjong

Microsoft Apps found on the Store may have their own language settings in the app's game settings, or it may read directly from your language settings in Windows 10.

I actually had Mahjong installed, and I could quite find the settings myself. In this case, you'll likely need to change the system language setting in Windows.

Note: This will change the ENTIRE Windows interface to the new language. Changing will require a reboot.

Hopefully it helps!

There the correct language setting is set but I have in the game, the wrong language

People reported this problem to Microsoft Chinese support forum and Microsoft employees replied that the problem is under investigation. We can do nothing but wait for a future fix... Also, according to the posts in this forum, seems that people using languages
other than English and Chinese also have this problem.

Another problem that annoys me is that if the system language is set to Chinese, theme switching no longer works and you can only use garden theme. This problem persists since the very first day and still no fix. It is interesting that Microsoft used modern
theme screenshots in Chinese version marketplace, but user have no access to this theme. I guess the problem is caused by the localization work, since theme change is working in Microsoft Solitaire Collection and Microsoft Mahjong...

Hi, thanks for your response. I changed the display language and preferred language to English, but emails from Microsoft remain in the Korean language.
