Tips you need to know
Once Arabic is installed, you will be able to type messages in Arabic or in English, to do so let's say you were typing an e-mail in English and you decided to type the rest in Arabic, just press and hold "Shift" button on your keyboard and press "Alt", and that will switch to "Ar", then you can do the same thing again (Shift + Alt) to switch back to English. Good luck!
How do I change the display language?
If your browser doesn't support Arabic or when you visit a website in Arabic it shows you just some weird signs and symbols, then you need to adjust your browser which can be done easily in order to display that page properly.
Go to the top of your browser where you have "File" "Edit" "View".... Select "View", then "Encoding" then "Arabic Windows" and that should do it, if the problem still exists, then that means the problem is not your browser, but on the page you're trying to view
