Windows is simply the only OS widely available to run on the vast majority of the machines that people own (PCs) and that's compatible with most software than people want to run. Windows basically has no competitors in the PC OS field. Linux is a fine OS, which I run myself, but it's not widely available in shops/preinstalled and doesn't run the majority of apps that people want MYOB, Quickbooks, iTunes, Microsoft Office etc.
