GNU/Linux users often emphasize extensive customization options as one of the greatest advantages of their OS – and rightly so.

This is especially true for KDE – the most customizable, and I'm sure many will agree, the most beautiful desktop environment. KDE is an all-round, professional, free and open source solution available in more than 60 languages, and today you'll learn that you can even install it on Windows.
