In an effort to appease EU regulators, Microsoft currently plans to ship in Europe "E versions" of Windows 7 without Web browsers. Smith said that Microsoft's proposal includes a "public undertaking" designed to promote interoperability between third party software and products including Windows, Windows Server, Office, Exchange, and SharePoint. "The Commission welcomes this proposal, and will now investigate its practical effectiveness in terms of ensuring genuine consumer choice," the statement added. Microsoft on Wednesday declared its next-generation Windows 7 operating system ready for delivery to computer makers. More than 10 million people joined in testing Windows 7 software in a voluntary test program, according to the US company.
