A US woman who earlier this year unsuccessfully tried to sue Microsoft for allegedly charging her extra to downgrade from Windows Vista to XP has brought another lawsuit against the software giant.
Emma Alvarado of Los Angeles, California, filed a complaint in a federal court last week, reports Computer World.
She has now accused Microsoft of breaking the city's unfair biz practice and restraint of trade laws by getting punters to buy a copy of Windows Vista or Windows 7 if they want to "downgrade" to the company's nine-year old Windows XP opereview system.
Alvarado has asked a California federal judge to grant the case class-action status, allowing the opportunity for other narked-off customers to sue Microsoft, if they so wish to.
She is demanding that Microsoft refund all sales derived from its downgrade option and said in the lawsuit that any members of the class - if a judge grants the case that status - should be awarded triple any actual damages meted out.
The complainant first filed a lawsuit against Microsoft on 11 February 2009, but it was dismissed in February this year.
