= Introduction

Advanced EFS Data Recovery (or simply AEFSDR) is a program to recover (decrypt) files encrypted on NTFS (EFS) partitions created in Windows 2000, Windows XP and Windows Server 2003. Files are being decrypted even in a case when the system is not bootable and so you cannot log on, and/or some encryption keys (private or master) have been tampered. Besides, decryption is possible even when Windows is protected using SYSKEY. AEFSDR effectively (and instantly) decrypts the files protected under Windows Server 2003 (Standard and Enterprise), Windows XP (including Service Packs 1 and 2) and all versions of Windows 2000 (including Service Packs 1, 2, 3 and 4).


= Requirements

- Windows NT 4.0, Windows 2000, Windows XP or Windows Server 2003
- Administrator privileges (for direct disk access).


= Known problems and limitations

- The program can decrypt protected files only if encryption keys (at least, some of them) are still exist in the system and have not been tampered.
- Only "Basic" (but not "Dynamic") NTFS partitions are supported.
- For files encrypted on Windows 2000, if Account Database Key (SYSKEY) is stored on floppy disk, or if "Password Startup" option has been set, you should know/have one of the following in order to be able to decrypt the files:
  - startup password or startup floppy disk
  - the password of user who encrypted the files
  - the password of Recovery Agent (if one is availbale)
- If password of the user (who encrypted the files) have been changed after encryption, you may need to enter the old password into the program.
- If files were encrypted under Windows XP (with or without SP1/SP2) or Windows Server 2003, the password of user who encrypted the files (or Recovery Agent) is needed for decryption.
- The program has been tested only on files encrypted under U.S. version of Windows; if any other (international) version has been used, correct work is not guaranteed.

= Registration

Unregistered (trial) version of AEFSDR has some limitations (see help file for more information). After you register (look at "order.txt" for details), we'll send you your personal registration code. To enter it into the program, just press the "Register" button on the program toolbar; the program will show the small window dialog asking you to enter the code. If the code is correct, AEFSDR shows the message that it is registered now, and so since than has the full functionality.
