The HKEY_CURRENT_CONFIG Key
The HKEY_CURRENT_CONFIG registry root key was first introduced with the release
of the Windows NT 4.0 operating system. This key contains configuration data for the
currently used hardware profile. Actually, this key is an alias that references the
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Hardware Profiles\Current
registry key.
The HKEY_CURRENT_CONFIG registry key was introduced with the release of
Windows NT 4.0 in order to provide backward compatibility with the
HKEY_CURRENT_CONFIG root key present in Windows 95. Now that the
HKEY_CURRENT_CONFIG tree is present both in Windows 9x and Windows
NT/2000/XP/Windows Server 2003 registries, all applications designed for Windows 95
will also work under Windows NT-based operating systems.
Fig. 7.22
illustrates the HKEY_CURRENT_CONFIG registry key structure. This
screenshot demonstrates that the HKEY_CURRENT_CONFIG key simply represents a
symbolic link to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Hardware
Profiles\Current registry key.
