This article provides information on how to identify the version of Distributed Component Object Model (DCOM) that is installed on Microsoft Windows 95-based, Microsoft Windows 98-based, and Windows Millennium-based computers.


You can determine which version of Dcom95 or Dcom98 is installed on a Windows 95, Windows 98, or Windows Millennium Edition-based computer by checking the registry. If DCOM is installed on the system, the default value of the registry key

  • - a - major operating system version
  • - b - minor operating system version
  • - c - minor file version
  • - d - major file version
