"The State Plaintiffs and the TC (technical Committee) are currently testing beta versions of upcoming Internet Explorer 9 and Windows 7 Service Pack 1 releases for compliance with the Final Judgments," the report indicates. The report also mentions that Microsoft continues to work on the Technical Documentation for the next major versions of Windows and Windows Server.
