Microsoft's Internet Explorer 7 will rely on certain internal security changes from Windows XP Service Pack 2, this means that Windows 2000 users won't be able to run IE7. The company says bringing IE7 to Windows 2000 is too complex because the Windows 2000 OS doesn't feature certain security features.
Company officials also noted that Windows 2000 is moving into the "Extended" support phase of Microsoft's product lifecycle as of June 30, 2005.
"It should be no surprise that we do not plan on releasing IE7 for Windows 2000," IE program manager Chris Wilson wrote on the Internet Explorer Web log.
The first beta version of Internet Explorer 7 will be released in June. More details at BetaNews
