EFS based Advanced Data Recovery system can quickly decrypt files that are shielded with EFS. And you got to admit that they do this job pretty efficiently. The hard drive is scanned sector by sector. The EFS based Advanced Data Recovery system can locate those encrypted files and the currently available encryption keys. It can decrypt all the protected files as well. If you get direct accessibility to the file system this allows Advanced EFS Data Recovery system to easily recover the encrypted files even in the grimmest cases when the data loaded disk is solely available without any valid user account to effectively log into the system.
The system is also effective in the instances some the encryption keys somehow were tampered with. Instant accessibility is an important issue here, though. If you have the EFS based Advanced Data Recovery system at your disposal, you will get instant accessibility to the EFS-shielded files most often. This product has been designed to recognize the weaknesses of the EFS encryption weakness in Windows 2000, which allows the fastest possible recovery of different types of encrypted files. Providing a legit password to the user account (as an alternate, you can use a formerly used password if that password was reset by the system administrator, which causes EFS-protected files to turn inaccessible) or just an account serving as an effective data recovery agent (i.e. Administrator account by default) could oftentimes provide a quick decryption of those protected files.The improved Professional edition is capable of locating master as well as private keys within those deleted files too. It can scan the entire disk by sector and use patterns for locating the keys, which allows the recovery of reformatted disks as well as that of the overwritten Windows installations.
