Microsoft Encrypting File System (EFS) is an integral part of Microsoft Windows operating systems that enables users to protect their files against unauthorized access even from those who gain physical access to the hard disk or the computer that contains the encrypted files. Advanced EFS Data Recovery decrypts the protected files, and works in all versions of Windows 2000, XP, 2003, Vista, Windows Server 2008 and Windows 7. The recovery is still possible even when the system damaged, is not bootable, or when some encryption keys have been tampered with. Advanced EFS Data Recovery recovers EFS-encrypted data that becomes inaccessible because of system administration errors such as removing users and user profiles, misconfiguring data recovery authorities, transferring users between domains, or moving hard disks to a different PC.
