 *   02/06/2001	rodtoll	WINBUG #293871: DPLOBBY8: [IA64] Lobby launching a 64-bit 
 * 						app from 64-bit lobby launcher crashes with unaligned memory error. 
 *   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).
