Ferrari, Infiniti and Porsche on your PC
Themes include Ferrari, Infiniti and Porsche, which can be downloaded to customise your PC. Bike riders can opt for a theme from Ducati.
A theme is a combination of pictures, colours, and sounds on your computer. It includes a desktop background, a screensaver, a window border colour, and a sound scheme. Some themes might also include desktop icons and mouse pointers.
You can find these themes and more at Microsoft's Personalization Gallery now.
Infiniti's theme package includes pictures of its Essence concept car, which was unveiled at the Geneva motor show earlier this year.
The Windows 7 operating system was launched last week.
