The Windows Registry

The Windows Registry replaces .ini files. It is a place where programs store the data they need to run. Eg, configuration settings.

Some key facts to remember.

Root Keys

[P] – primary key
[A] – alias to some other key in the registry

  1. [A] HKEY_CLASSES_ROOT (HKCR)
    • On Windows 2000 and above, HKCR is a compilation of user-based HKCU\Software\Classes and machine-based HKLM\Software\Classes. If a given value exists in both of the subkeys above, the one in HKCU\Software\Classes takes precedence.
  2. [A] HKEY_CURRENT_USER (HKCU)
    • a link to the subkey of HKEY_USERS that corresponds to the user; the same information is accessible in both locations
  3. [P] HKEY_LOCAL_MACHINE (HKLM)
  4. [P] HKEY_USERS (HKU)
  5. [A] HKEY_CURRENT_CONFIG (HKCC)
    • It is a handle (alias) to the key "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Hardware Profiles\Current" (only exists in Windows 9x/Me and NT-based versions of Windows)
  6. HKEY_PERFORMANCE_DATA (only in NT-based versions of Windows, but invisible in the Windows Registry Editor)
  7. HKEY_DYN_DATA (only in Windows 9x/Me, and visible in the Windows Registry Editor)
