A complaint made against Microsoft by The Taiwanese Consumer Foundation, which claimed that the company effectively using its monopoly to force sales of Vista is being investigated by the Taiwanese Fair Trade Commission.

Around 56% of people purchasing new machines, with Vista on, would have XP on their new box, whereas 67% thought that Microsoft shall continue to offer XP.

In Taiwan, XP is still available on some new, lower-spec machines.

To interpret the competition law that a company had to sell a product for ever would be strange said an anti trust lawyer while speaking to news persons.

Microsoft had tussled with the Taiwanese authorities before and in 2003 the company settled with the Fair Trade Commission. If found guilty Microsoft could be fined 25 m Taiwanese Dollars or 427,000 pounds.
