Change the display language on window Computers

The display language is the language that Windows uses in wizards, dialog boxes, menus, Help and Support topics, and other items in the user interface. Some display languages are installed by default, and others require you to install additional language files. When you change the display language, it is changed for your user account and is not changed on the Welcome screen.
