A spokeswoman for the European Commission, Amelia Torres, said today that Microsoft "always informs antitrust authorities when it is about to launch a new product, and that includes the European Commission."
Microsoft contacted the commission in May, inviting it to raise questions. The company had replied to the questions the commission raised, said Torres.
The European Commission confirmed on 30 August that it would merge two antitrust investigations into Microsoft's operating systems, but that it would not seek to block the launch of Windows XP.
The two investigations both covered accusations that Microsoft had violated European antitrust rules by using illegal practices to extend its PC operating system market position into the market for low-end server operating systems.
