HKEY_CLASSES_ROOT. HKEY_CLASSES_ROOT or HKCR is an alias (i.e. a reference) to HKEY_LOCAL_MACHINE\Software\Classes. A separate root key is added mainly so software developers have direct access to this data without dipping in to HKLM. HKCR contains data related to applications, shortcuts, and file extension associations.
The following registry keys are located under the HKEY_LOCAL_MACHINE hive: 1  HKEY_LOCAL_MACHINE\BCD00000000. 2  HKEY_LOCAL_MACHINE\COMPONENTS. 3  HKEY_LOCAL_MACHINE\DRIVERS. 4  HKEY_LOCAL_MACHINE\HARDWARE. 5  HKEY_LOCAL_MACHINE\SAM. 6  HKEY_LOCAL_MACHINE\Schema.
