The keyboard layout controls what characters appear when a key is pressed. While the standard keyboard layout is QWERTY style, Windows allows you to easily add and change different languages and layouts depending on your preference. The keyboard layouts are controlled by the Language Bar, available through the Control Panel. Before changing keyboard layouts, you must enable the layouts you want to use. You can also switch back to the standard QWERTY layout at any time.
Click on "Control Panel" from the Start menu. Type "keyboard layout" into the search bar, and click on "Change keyboards or other input methods" under the Region and Language heading to open the Region and Language dialogue box.
Click on "Change keyboards..." under the Keyboards and Languages tab. Click on "Add..." under the General tab to open the Add Input Language dialogue box.
Find the language you want to add and expand its tree, then expand the "Keyboard" subtree for that language, and finally click in the check box next to the keyboard layout you want to add. You can repeat this step to add multiple language layouts.
Click on "OK" in the Add Input Language dialogue box, then click on "OK" in the Text Services and Input Languages box, then finally click on "OK" in the Region and Language box.
Change the keyboard layout by clicking on the current language selection in the Language Bar on the right of the taskbar. The standard layout is marked EN. From here, you will be presented with a list of your selected keyboard layouts, any of which can be selected by clicking on it. Clicking on "EN English (United States)" will revert to the standard QWERTY English keyboard layout.
