unable to decrypt a file after win vista has been formatted.

[Vicky-Aryan]

Hi,
i am using windows vista business in my sony vaio laptop. nd i made some
of my files encrypted during normal use with the help of fingerprint
sensor without providing the additional password , only swiping the
finger on
sensor could
unlock those files but it can not be unlocked by a password bcoz i didnt
provide it at the time of encryption. nd then recently i formatted my
windows
vista without decrypting those locked files and now i have installed new
copy
of windows vista on my laptop , but i m unable to unlock the encrypted
files .
cud anyone pls help me to know the solution for decrypting the files
again.
pls mail me the solution.
i seriously need your help
nd i lost all the keys nd certificates of previous windows vista nd there
is
no backup of any key or certificate.

I'm afraid that you are out of luck, unless you can find some way to recover
the keys / certs from the previous installation of the operating system. If
you are going to use EFS you MUST back up your certificates OR back up your
encrypted data in unecrypted form on external media. To do otherwise is to
risk the experience you are now having.

BTW, if your original OS installation could be recovered (You could restore
it from a backup, if you've made one.), then you would be able to get access
again to your data.
