Windows Nt Registry
As I mentioned previously, regedt32 can search in only the current subtree. The data in HKEY_LOCAL_MACHINE \System--which is the System hive--is organized into control sets that contain a complete set of parameters for devices and services as described in this section. Windows NT creates a default hardware profile (called Original Configuration). Order within groups is specified by using Tags and GroupOrderList.HiveListThe location of the files that contain Registry information. navigate here
REG_DWORD Double word. One particularly interesting subkey is HKLM\SOFTWARE\Microsoft\Windows NT\Current Version. You can use regedt32 in a read-only mode: Start regedt32, and select Options, Read Only Mode.

- After this, the user needs to manually remove any reference to the uninstalled program in the registry.

I look forward to seeing what cool modules the community can cook up that utilizes the library. Entries that appear under the DeviceMap subkeys include values that refer to entries in the Services subkey in the control set. Because user-based Registry settings are loaded from a user-specific path rather than from a read-only system location, the Registry allows multiple users to share the same machine, and also allows programs Hkey_current_config HKEY_USERSContains all actively loaded user profiles, including HKEY_CURRENT_USER, and the default profile.
HKEY_DYN_DATA This key is used only on Windows 95, Windows 98 and Windows ME. It contains information about hardware devices, including Plug and Play and network performance statistics.

I used 'reg SAVE HKLM\$HIVE $HIVE.hive', substituting $HIVE for the actual hive name, then download'ed the copied hive in meterpreter. Hkey_users However, if you need to create a new value entry, you must know the correct data type. It has many of the same functions as Regedt32 and an expanded search capability.
We now have the option of using the Volume Snapshot Service, or VSS, to create a copy of a hive while locked.
