Each release of Windows comes with one or more preset theme. Even though the main aim of a Windows theme is to make your session easier to work, without much strain on your eyes, many prefer hot colors and a striking theme that might just uplift their moods or to show off to their friends. You would have noticed that the default themes of Windows have always contained unsaturated colors for different elements. This is especially so that you do not stress out your eyes. Still, you have the option to customize the themes and to download more. You can customize Windows theme using the Display properties, Appearance tab on Windows 98Se and Windows XP. The tab allows you to change the colors of different elements of Windows – desktop, application background, size and font of icons, and much more. Once done, you can also click the General tab of the same dialog and save the custom theme.
The above option offers you limited options. If you wish your XP based computer to look like Windows 7, here is a review of some of the best Windows themes I came across on the Internet.
