A program to recover (decrypt) files protected with Windows EFS (Encrypting File System). 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 have been tampered.

Encryption keys (private or master) have been tampered. Besides, decryption is possible even when Windows is protected using SYSKEY.
