Quoting research from various industry analysts, Microsoft warned that users who install unlicensed or counterfeit software on their PCs are 73% more likely to suffer data loss or damage than users of legitimate software. The company also cited a 2006 IDC study that found that 25% of counterfeit software attempted to install unwanted or malicious code when downloaded. In response, Microsoft is launching a series of educational initiatives and enforcement actions in over 70 countries to combat the threat. Microsoft is calling its anti-piracy campaign Consumer Action Day. Microsoft has posted additional information about the risks of counterfeit software and its efforts to fight the problem at microsoft.com/howtotell.
