This article lists the version numbers of Microsoft XML Core Services or the Microsoft XML
parser (MSXML). Different versions of MSXML are included with various Microsoft
products, such as Microsoft Windows, Microsoft Internet Explorer, Microsoft Office, and Microsoft SQL Server. MSXML is also updated when you install software updates for various Microsoft products.
Microsoft provides several different XML parsers. The MSXML parser is included in the Msxml.dll file, the Msxml2.dll file, the Msxml3.dll file, the Msxml4.dll file, the Msxml5.dll file, the Msxml6.dll file, and one or more resource files. Notice that Windows HTTP Services (Winhttp*.dll) is also included with some versions of MSXML.
The Microsoft XML parser is a Component Object Model (COM)
implementation of the W3C DOM model. Two versions are associated with each
parser: the release version of the MSXML parser and the actual file version of
the DLL that contains the parser. The release version of the MSXML parser (for
example, versions 2.5, 2.6, 3.0, 4.0, 5.0, and 6.0) identifies the milestone of
development.
Msxml6.dll, Msxml6r.dll (the last DLL is a resource-only DLL)
6.30.7600.16385
Notes
MSXML versions 1.x and 2.x are no longer supported by
Microsoft.
MSXML 3.0 support follows the support policy of the OS into which it is built.
MSXML 4.0 is supported by Microsoft only if you are running Service Pack 3 (SP3).
MSXML 5.0 is supported by the Microsoft Office lifecycle policy.
MSXML 6.0 support follows the support policy of the OS into which it is built or onto which it is installed.
This table includes the version of MSXML that is included in security updates that were released since October 10, 2006.
