Internet Explorer 6

Internet Explorer 6 is the sixth version of Internet Explorer that was introduced alongside Windows XP and Windows Server 2003 and was the longest running version of Internet Explorer until IE 7's release five years later. IE 6 lacks many common features such as support for transparent PNG images. This is the last version of Internet Explorer that is compatible with Windows NT 4.0 (albeit requiring SP6a), Windows 98, Windows 2000, and Windows Me; the succeeding versions required Windows XP SP2 and Windows Server 2003 SP1 or newer. This is the first version of Internet Explorer to ship in the IA-64 and x64 architectures, alongside x86.

It was also included in the Windows Security Update CD for Windows 98 build 1998A, Windows 98 SE build 2222B and Windows Me build 3000A from February 2004.

These system requirements apply to both the RTM and SP1.

Quirks

 * On Windows NT 4.0, System Properties reports "IE 5 6.0.2800.1106" (in this case for IE 6 SP1). This field is normally used to report the version of an installed copy of Microsoft Plus! if installed. This can be fixed by editing the appropriate entry in the registry:
