How Do I Change Skype to English?by Kenneth Coppens
When you install Skype on your computer, it opens in the language that you chose for your computer's operating system. If Windows is in a different language, or if someone changed Skype to a different language on your computer, you can have Skype appear in English at any time. The process takes just three clicks of your mouse. While these instructions are in English, the menus in Skype will of course be translated into the chosen language until you reset it to English.
Click the Skype "Tools" menu and select "Change Language" from the drop-down menu.
Choose English from the list of languages.
Restart Skype to complete your changes.
