 *   02/21/2000	mjn		Created
 *   06/07/2000	rmt		Bug #34383 Must provide CLSID for each IID to fix issues with Whistler
 *   06/15/2000	rmt     Bug #33617 - Must provide method for providing automatic launch of DirectPlay instances 
 *   07/21/2000	RichGr  IA64: Use %p format specifier for 32/64-bit pointers.

 *   08/30/2000	rmt		Whistler Bug #171824 - PREFIX Bug
 *   04/12/2001	VanceO	Moved granting registry permissions into common.
 *   06/16/2001	rodtoll	WINBUG #416983 -  RC1: World has full control to HKLM\Software\Microsoft\DirectPlay\Applications on Personal
 *						Implementing mirror of keys into HKCU.  Algorithm is now:
 *						- Read of entries tries HKCU first, then HKLM
 *						- Enum of entires is combination of HKCU and HKLM entries with duplicates removed.  HKCU takes priority.
 *						- Write of entries is HKLM and HKCU.  (HKLM may fail, but is ignored).
 *						- Removed permission modifications from lobby self-registration -- no longer needed.  
 *   06/19/2001 RichGr  DX8.0 added special security rights for "everyone" - remove them if they exist.
