When u Encrypt files,,,, windows stores ur Private key in registry, and it can be Backedup in this way >> http://www.jsiinc.com/SUBI/tip4400/rh4474.htm

BUT u can backup it ONLY when ur hard drive is not formatted,,,, coz once u have formatted the registry, the key information has been erased,,,, and that's the reason u are unable to de-crypt those files now =\

No, there is no way to decryt those files.

If there was a way to decrypt the files without the proper EFS key it wouldn't be secure.

Good luck.

When ransomware hits your clients, what do you do?

MSPs: Endpoint security isn’t enough to prevent ransomware.
As the impact and severity of crypto ransomware attacks has grown, Webroot fought back, not just by building a next-gen endpoint solution capable of preventing ransomware attacks but also by being a thought leader.

Hi, you can always try:
Advanced EFS Data Recovery 2.0

Information:
This is a program to recover files encrypted on NTFS partitions created in Windows 2000 and Windows XP. Files are decrypted even when the system is not bootable.
Decryption is possible even when Windows is protected using SYSKEY. AEFSDR decrypts the files under all versions of Windows Server 2003, Windows XP and Windows 2000.

Hate to rain on the parade but this won't help any.

From the product documentation:

     = 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.

In this case *none* of the encryption keys exist since the machine was formatted and then the OS was reinstalled.

Possibly a useful utility if the OS isn't bootable for some reason but not in this case.

Sorry.
