Folder/Registry Hive	Description
HKEY_CURRENT_USER	Contains the root of the configuration information for the user who is currently logged on. The user folders, screen colors, and Control Panel settings are stored here. This information is associated with the user profile. This key is sometimes abbreviated as "HKCU."
HKEY_LOCAL_MACHINE	Contains configuration information that is particular to the computer (for any user). This key is sometimes abbreviated as "HKLM."
HKEY_CLASSES_ROOT	Is a subkey of HKEY_LOCAL_MACHINE\Software . The information that is stored here verifies that the correct program opens when you use Windows Explorer to open a file. This key is sometimes abbreviated as "HKCR." Starting with Windows 2000, this information is stored under both the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER keys. The HKEY_LOCAL_MACHINE\Software\Classes key contains default settings that can apply to all users on the local computer. The HKEY_CURRENT_USER\Software\Classes key contains settings that override the default settings and apply only to the interactive user. The HKEY_CLASSES_ROOT key provides a view of the registry that merges the information from these two sources. HKEY_CLASSES_ROOT also provides this merged view for programs that were designed for previous versions of Microsoft Windows. To change the settings for the interactive user, make the changes under HKEY_CURRENT_USER\Software\Classes instead of HKEY_CLASSES_ROOT . To change the default settings, make your changes under HKEY_LOCAL_MACHINE\Software\Classes . If you write keys to a key under HKEY_CLASSES_ROOT , the system stores the information under HKEY_LOCAL_MACHINE\Software\Classes . If you write values to a key under HKEY_CLASSES_ROOT , and the key already exists under HKEY_CURRENT_USER\Software\Classes , the system stores the information there instead of under HKEY_LOCAL_MACHINE\Software\Classes .
