BBC NEWS | Business | EU warns on Microsoft behaviour: "Microsoft has not done enough to comply with sanctions imposed for breaking European anti-trust rules, the European Commission (EC) has said.
The software giant was censured in 2004 for misusing its monopoly position in desktop PCs to extend its reach into other areas.
The firm agreed to a 497m euro ($660m, £345m) fine and to make its software work better with competitors' products.
But an EC spokesman said Microsoft was failing to deliver on its commitments."
