Customizing Hot Fix Properties

Microsoft lacks a well-published or standardized mechanism to track the installed hot fix information on Windows-based computers.  Instead, various registry locations have been used throughout the years for recording the hotfix installation information on Windows NT and later Windows versions.  

Hyena uses a customizable text file that can be used to store the registry key paths that will be used by Hyena to scan for hotfix information.  This information appears on the HotFix dialog on the Computer Properties dialog.  The name of this file is HYENA_HOTFIX_LIST.DAT and it must be found in Hyena's installation directory, or, if using a shared settings file, in the Shared Settings directory.  The sample file that gets installed with Hyena currently contains these key paths:

SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix

SOFTWARE\Citrix\Metaframe\CurrentVersion\HOTFIX

SOFTWARE\Microsoft\Windows NT\CurrentVersion\SP4\Hotfix

SOFTWARE\Microsoft\Windows NT\CurrentVersion\SP5\Hotfix

All of the registry locations are subkeys of HKEY_LOCAL_MACHINE.  This file can be modified with any text editor.
