Catalog Items and Sysgen Variables

The following table describes the catalog items you can use to add support for COM or Distributed COM (DCOM) to your OS.

Catalog item	SYSGEN variable	Description	Dependencies
COM	SYSGEN_OLE	Adds a standard implementation of COM and automation that supports only in-process free-threaded objects, support for CoCreateGuid, and structured storage functionality.	Requires about 100 KB to 200 KB of memory.
DCOM	SYSGEN_DCOM	Adds a full-featured "out of process" COM implementation equivalent to Windows NT 4.0 Service Pack 5 (SP5), including structured storage functionality. This catalog item does not add the DCOM component libraries. Note: DCOM in Windows Embedded Compact does not support DCOM Remoting, so you cannot create and host COM objects across a network.	Requires more than 700 KB of memory.
