Anyone ever try "EFS Key" to De-Encrypt NTFS files?

[NiGHTsC]

Passware EFS Key

Since both my bro and friend forgot to save the EFS key when formating windows, their encrypted files are not unable to open.

So I found this program from Passware, EFS Key.

Just wondering if anyone ever tried this program before? How long does it take to De-Encrypt an EFS file?

Cause currently I'm using VMware so I can have multi-windows without touching my main windows

and this program has been decrypting a TXT file for hours= =

We are all using XP Pro SP2.

Thank you

Just wondering how that works: the page you linked to says you have to know the key, and then it can decrypt the stuff.
