An anonymous reader writes "Microsoft has submitted the follow-up to Windows Vista to the committee that oversees its US antitrust compliance, to ensure the operating system is meeting the terms of the company's agreement with the government. According to last week's status report on the US antitrust case, Microsoft "recently supplied" the Technical Committee (TC) with a build of the OS, code-named Windows 7, and the TC will "conduct middleware-related tests on future builds" of the software. The move was revealed in papers filed in the US District Court for the District of Columbia. Those on the TC so far are the only ones privy to what the follow-up to Vista will look like, and Microsoft is mum on details of the software. But recent company moves and revelations hint at what can be expected from the software, which is due for release in late 2009 or early 2010. Lets hope Microsoft learns some lessons from the "Vista Capable" dilemma!!"
