Change your keyboard layout
You can customize your keyboard for a specific language or format by changing the keyboard layout. The layout controls which characters appear on the screen when you press the keys on your keyboard. Some input languages have several keyboard layouts; others have only one. For example, you can change your keyboard layout from the English QWERTY format to the English Dvorak format. After you change the layout, the characters on your screen might not correspond to the characters on your keyboard keys.
Before you can change the keyboard layout, you must add the input language and keyboard layout that you want to use to Windows. For more information, see Add an input language.
