I am a Belgian and my mother tongue is Dutch, but as an ITPro, I like to have my Windows 10 display language, Microsoft Store and Windows Apps language set to English (United States) with Belgian period (Azerty) as my preferred keyboard setting. Normally, you do not need to change this language settings after the initial setup but there might be some situations where you do. When you manually install and setup Windows 10 on a new device, you are asked to choose a default system language.
