Quote:The latest Canary and Dev builds released by Microsoft on both platforms come with such capabilities, and the official changelog confirms this is indeed possible in Microsoft Edge:
“Added more languages that you can display Microsoft Edge in.”
 
I tested this new feature in the Dev build of Microsoft Edge and it indeed works like a charm for specific languages, including French and Spanish. Support for more languages, such as Italian and others, is expected in the coming updates.
 
To change the language in Microsoft Edge, you must first update to the latest version of the browser, regardless of the channel that you’re currently using. Once you do this, in the browser follow this path:
Microsoft Edge > Menu > Settings > Languages > Add languages

After you install the language that you want to use Microsoft Edge in, click the three-dot menu next to it and hit the option that reads “Display Microsoft Edge in this language.”
A reboot of the browser will be required to see the new language activated in the browser.
