KB 940848 will most likely become a required preinstallation checkpoint for SCCM 2007 due to the following issue with the current shipping versions of MMC with Windows Server 2003:
Some items on a shortcut menu are missing when you right-click an item in an MMC snap-in.
For example, when you right-click the Task Sequences node, the following menu items are missing:
Create Task Sequence Media
These menu items appear only if you right-click this node again.
It also fixes an issue with unexpected termination of MMC.EXE with a generic Visual C++ error as the only indicator of a problem.
