Bonnie MacNaughton, senior attorney for Microsoft, said the company estimates that more than one-third of all copies of its software are counterfeit, based on a recent joint report released by the Business Software Alliance and research firm IDC. The study found that 35 percent of software worldwide is pirated. In North America alone, the piracy rate for software is 22 percent. "We consider that to be a staggering number," said MacNaughton.
Microsoft are keen to stress that customers who discover they have a counterfeit copy of Windows will either be given a free version of the operating system or can purchase it for a discounted price, but to get this they will have to fill out a counterfeit report identifying the source of the software.
