Class action status has been denied by a U.S. federal court to the lawsuit accusing Microsoft Corporation of misinforming buyers about the computers which could run multiply features which had been parts of the operation system used for Windows Vista.

According to court documents released on Wednesday, Judge Marsha Pechman of the U.S. District Court in Seattle permitted the suit to advance on behalf of the individual accusers. The facts showed that Microsoft authorized computer manufacturers to stick the “Windows Vista Capable” signs on some PCs.

The sticker wanted to show the buyers that the Windows XP operating system could have been upgraded to the operation system from Vista. Dianne Kelley, who leads the accusers in the trial, stated that the marketing campaign made by Microsoft was misleading.

Kelley explained that the PCs having the sticker on them could only be upgraded to “Windows Home Basic,” which is a version of Vista that has no features of the Premium version. Those computers hadn’t had a “Premium Ready” designation. Yet, Microsoft tried to explain that these distinctions which made them come on trail had been very clearly showed in the marketing campaign.

In the end, the court reached the conclusion that the accusers couldn’t demonstrate their claims and the fact that these had been common among the entire class of consumers who had bought the “Windows Vista Capable” marked ones, but which didn’t have the “Premium Ready” label. Yet, all the accusers were permitted to go on with separately suits.

Pechman said the ruling that the court had denied the class action status didn’t mean that it comments on the merits that the accusers might have had.
