SHDOCVW Versions

SHDOCVW.DLL has so far existed in at least seven variations considered by Microsoft to have sufficient external impact to deserve at least a difference in the minor version number.

SHDOCVW Version Distribution
Internet Explorer Windows NT
4.70 3.0, 3.01, 3.02 Windows 95 OSR2  
4.71 4.0    
4.72 4.01 Windows 98  
5.0 5.0, 5.01 Windows 98 SE Windows 2000
5.50 5.5 Windows Me  
6.0 6.0, 7.0, 8.0   Windows XP,
Windows Server 2003,
Windows Vista
Windows Server 2008
6.1     Windows 7

Microsoft documents the existence of earlier versions that have not been found for this survey. See for instance the page Licensing and Distribution in documentation of the WebBrowser Control. After noting that “because the Internet Explorer browser is implemented in Shdocvw.dll, the version of this DLL can be used to determine which version of Internet Explorer is installed”, it lists SHDOCVW versions up to and including 6.0 for the original Windows XP, but stretching as far back as 4.40 for Internet Explorer versions 1.0 and 2.0.


Though the next table fusses over such details as build numbers and dates, it is certainly not meant as a comprehensive list even of builds that had formal, public releases. For that, consult Microsoft, who manufacture the software and are surely best able of anyone to present a definitive record. Bear in mind, however, that if Microsoft’s published documentation could sensibly be relied on as either comprehensive or accurate, then you could not now be reading these notes.

Builds are arranged in increasing order of the file version as recorded in the executable’s resources. This version number is readily visible using Windows Explorer either in a so-called infotip for the file or by accessing the Version tab in the Properties dialog for the file. Programmers know this version number as coming from the so-called root block of the version-information resource, specifically from the dwFileVersionMS and dwFileVersionLS members of a VS_FIXEDFILEINFO structure.

The date stamp shown for each version is more obscure. File dates are easily modified after the executable is built and are anyway liable to be shown differently when read from different time zones. However, there is in each executable’s header a date stamp which is set when the executable is built and is not commonly changed afterwards. It is readily accessible to anyone with programming knowledge and appropriate tools, e.g., Microsoft’s own DUMPBIN utility.

In the days when Microsoft had two operating systems named Windows, most Internet Explorer versions supplied the executable separately for Windows and NT (and in some cases with a further separation for NT 4.0 and Windows 2000). Where two date stamps are presented on the same row for an Internet Explorer release, it means that the Windows and NT executables differ only in the file header’s date stamp and checksum (and that the date stamps are from the same day).

The Internet Explorer 8 packages for Windows XP and Windows Server 2003 each have the same SHDOCVW as have the corresponding packages for Internet Explorer 7. The Internet Explorer 8 package for Windows Vista has no SHDOCVW.

The SHDOCVW executables for Windows Vista SP1 and Windows Server 2008 are identical.
