Best seller Windows XP
Within the first two months, Microsoft's new Windows version XP has been sold 17 million times. Both the retail versions and the copies pre-installed on PCs are included in the sales figures.
Windows XP is the bestseller among Microsoft operating systems, according to Bill Gates. In the time since its introduction on October 25, 2001, the pre-installations of Windows XP are 300 percent higher than Windows 98 and 200 percent higher than Windows ME. Bill Gates speaks of Windows XP as the engine of the IT industry, because he wants to have observed higher sales figures for printers, digital cameras and other 'multimedia peripherals' since its introduction.
