* ==== == ======
* 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.
* 08/18/2000 rmt Bug #42751 - DPLOBBY8: Prohibit more than one lobby client or lobby app per process
* 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.
