On April 3, 2000, a judgment was handed down in the case of "United States v. Microsoft Corp.", calling the company an "abusive monopoly" and forcing the company to split into two separate units. Part of this ruling was later overturned by a federal appeals court, and eventually settled with the U.S. Department of Justice in 2001. On June 15, 2000, the company released a new version of its hand-held operating system, Windows CE 3.0. The main change was the new programming APIs of the software. Previous versions of Windows CE supported only a small subset of the WinAPI, the main development library for Windows, and with Version 3 of Windows CE, the operating system now supported nearly all of the core functionality of the WinAPI. The next update to the consumer line, Windows ME (or Windows Millennium Edition), was released on September 14, 2000. It sported several new features such as enhanced multimedia abilities and consumer-oriented PC maintenance options, but is often regarded as one of the worst versions of Windows due to stability problems, restricted real mode DOS support and other issues.
