Well, Microsoft is heading for some rough times with their generally loathed Windows Genuine Advantage. Here's what DailyTech had to say: The new suit lists its plaintiff as Engineered Process Controls and Univex, along with citizens Edward Misfud, David DiDomizio, and Martin Sifuentes, who are listed as owners of licensed copies of Windows XP running WGA. The suit alleges WGA is spyware and that Microsoft misled consumers by labeling it as a critical security update. The plaintiffs maintain Microsoft did not make users aware that WGA frequently contacted its central servers. Not good, and you would think after Sony's rootkit fiasco companies would be much more careful about what means they use to protect their assets.
