Microsoft had marketed Windows 98 as a "tune-up" to Windows 95, rather than an entirely improved next generation of Windows. Upon release, it was generally well received for its web-integrated interface and ease of use, as well as for addressing issues that had been present in Windows 95, though users had pointed out that it was not significantly more stable than its predecessor. It saw one major update called Windows 98 Second Edition (SE) on May 5, 1999, and was succeeded by Windows Me in 2000. It sold an estimated 58 million licenses, and Microsoft ended mainstream support for both Windows 98 and 98 SE on June 30, 2002, and ended extended support on July 11, 2006.
