Advanced EFS Data Recovery (AEFSDR) 3.0 for Windows makes it easy to recover (decrypt) files encrypted on NTFS (EFS) partitions created in Windows 2003, XP, and 2000. With AEFSDR, protected files can be decrypted, even when the system is not bootable so you cannot log on, or when some encryption keys (private or master) have been tampered with. In addition, decryption is possible even when Windows is protected using SYSKEY. AEFSDR effectively (and instantly) decrypts the files protected under all versions of Windows 2000, Windows XP (including Service Pack 2), and Windows 2003.
