Using RegFileExport

RegFileExport is a console application designated to be used by advanced users. RegFileExport accept 2 - 3 parameters, according to the following syntax:

RegFileExport [Registry File] [Destination .Reg File] {Registry Key}

{Registry Key} is optional, if the key is specified, only this key and all its subkeys will be exported into the .reg file. Otherwise, the entire file will be exported.
if [Destination .Reg File] is an empty string ("") the Registry data will be sent to the standard output.

Examples:
RegFileExport "E:\Windows\system32\config\SOFTWARE." "f:\temp\reg1.txt" "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion"
RegFileExport "SOFTWARE" "" "Software\Microsoft\Windows NT\CurrentVersion"
RegFileExport "NTUSER.DAT" "ntuser-reg.txt"
RegFileExport "NTUSER.DAT" "ntuser-reg.txt" "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion"

More Information

  • RegFileExport can also export secret data that is only available for 'SYSTEM' account, like the password/security information stored in SECURITY and SAM Registry hives.
  • RegFileExport cannot export Registry data of your currently loaded operating system, because these files are locked by Windows.
  • On Windows XP - If you want to extract Registry infromation from previous restore points, you can find the Registry files of every restore point under C:\System Volume Information\_restore{guid}\RPxxx\snapshot. However, you must change the permissions of this folder in order to access these files, or alternatively, you can run cmd.exe as a SYSTEM account (with 'at' command), and then you'll be able to access this folder and the Registry files that are stored in it. Be aware that the _restore{guid} subfolder also has 'hidden' attribute.
