More Vista Blues for Microsoft?

The European Union (EU) has written to Microsoft to state its anti-competition concerns about the US giant's new operating system. EU Competition Commissioner Neelie Kroes is worried that the forthcoming Windows Vista system will not offer customers a real software choice.

Yet the letter does not mean the start of a formal inquiry, and Ms Kroes is responding to a query from Microsoft.

Microsoft had asked EU regulators to set out any Vista concerns it may have.
