Microsoft has angered Chinese computer users with its latest antipiracy move. On Tuesday, during its Global Anti-Piracy Day, Microsoft turned Windows Genuine Advantage loose on the Chinese people. Other users worldwide are familiar with WGA, which famously labeled legitimate users as pirates and disabled some features of their operating systems. One Chinese user complained that Microsoft had no right to hijack his computer. Another, a lawyer, actually filed an official complaint against Microsoft for hacking, and called Microsoft the biggest hacker in China.
