The story has been corrected on the wire and the third paragraph now reads as follows:

Plaintiffs in the suit, filed in April 2007 in a U.S. District Court in Seattle, claim that Microsoft's sticker program was an example of deceptive business practices and violated consumer protection laws. Earlier this week, attorneys for the plaintiffs filed a motion for narrowed class certification, requesting that the suit apply to anyone who purchased Windows Vista Capable PCs in Microsoft's Express Upgrade Guarantee program. They also are requesting the judge push back the trial date, which is currently April 13, to have time to consider the motion.
