A Los Angeles woman has filed suit against Microsoft over the fees charged by the company and its partners for downgrading computers from Vista to Windows XP. Emma Alvarado filed the suit over the $59.25 fee she was charged last year by Lenovo to downgrade to XP. In the suit, Alvarado claims Microsoft has eliminated competition in the operating system marketplace and has created a monopoly. She also claims that Microsoft charged the fees "in order to maintain, protect, and extend its market power in operating systems software into the next generation of personal computing, to lessen competition, and to enhance its monopoly position." Alvarado is seeking class action status for her suit and has not specified the damage amount.
