As of 2014, Microsoft's Windows Live Hotmail is available in more than 100 different languages, including Spanish, French, Mandarin Chinese and German. No matter what language was used when signing up for Hotmail, the language can be changed at any time in the Options menu.
To change Hotmail to a different language, click on the Settings icon in the toolbar, and then click on the Options button. In the Options window, click on the Language button, and then select the appropriate language from the list. After selecting the language, click the Save button. The language preference stays the same until it is changed.
