How to Enable an Arabic Keyboard
In Windows 7 and Vista, you can change the input language and keyboard layout so you can edit documents in multiple languages. By configuring your keyboard to an Arabic keyboard layout, the keys you press appear in Arabic characters. Before changing your keyboard layout, you have to install the Arabic input language--a process that takes minutes to complete using a simple wizard.
Click the "Start" menu on the taskbar and click the "Control Panel" to launch the Control Panel.
Launch the "Regional and Language Options" by clicking "Clock, Language and Region," and then clicking "Regional and Language Options."
Click the "Keyboards and Languages" tab and then click the "Change Keyboards" option. Click the "Add" option under "Installed services."
Double-click the Arabic language option. Double-click the text services you want to add and select the text services options you want to add. Click "OK" to save your changes.
Click the "Input language" option on the language bar located on the taskbar. If you cannot see the language bar, right-click the "taskbar," select "Toolbars," and then select "Language Bar."
Click the "Keyboard layout" option and select the Arabic keyboard layout.
