How to Switch a Keyboard Back to English
If you run a business that deals with people of all nationalities, you will inevitably encounter foreign languages and may sometimes have to write certain foreign words. Windows 7 gives you the ability to add foreign keyboard layouts, so you can easily type foreign characters or symbols without resorting to Windows' Character Map. However, when you're finished accessing these special characters, you will want to return to your native English language. This is done through the Language Bar, which appears only when more than one language is installed.
Click the "Language Bar," located to the left of your Windows 7 notification area by default, to bring up the language selection menu. The Language Bar will appear as a two-letter symbol, indicating the currently selected language.
Click "EN" to switch back to English.
Press "Alt-Shift" to toggle between language modes without accessing the Language Bar. As an example, if you only had two languages installed, pressing "Alt-Shift" would immediately return you to English mode.
