The user interface components of Windows, such as sound events, backgrounds, icons, fonts, and mouse pointers, are called elements. A theme is a set of elements that create a coordinated look for Windows. To modify a set of elements all at once, you simply change the theme.

You might also have heard of skins. The terminology can be confusing, because a skin and a theme are often used interchangeably. However, the majority of folks agree that a theme is a collection of customized elements for the operating system and a skin is a visual customization for a stand-alone application.

One great software that is capable to change aspect of your windows theme is TuneUP Utilities 2009: with it you can:

• change the boot screen theme (also called startup logo or bootskin)
• change the logon or login theme
• change the desktop theme (with icons, cursor, buttons, frames, sounds, desktop wallpaper...)

You don't have to patch any uxtheme.dll or other files. So it's a quite simple and secure operation that you could do every day if you wants. Desktop wallpaper are included and visual styles are applied as soon as you press a button.

You can also customize your fvourite theme, or use your personal image or photo and change it every time you want.

Other software are more complicated and may not function on most up to date operating system.
