I have a major problem on my hands.

I use the encryption feature of winxp quite frequently to protect my files, as I am constantly sharing files over LAN. Recently, I formatted my HDD and re-installed widows. Before doing go I copied all my data to another partition. Now, with winxp reinstalled and running, I no longer have permission to access my encrypted files!!! As the encryption setting in winxp is such that only the user who encrypts can decrypt, i'm locked out!! Since I've reinstalled, the user under which it was encrypted, even thought it was me, does not exist anymore. So I cannot use the files nor can I decrypt them.

Is there anyway to get out of this mess? Those files are very important, and I can't risk losing them.

peace...

If you couldn't risk using them, you should not have used EFS. Now there is no chance of recovering them. Sorry!

If those files are very important then you must have taken a backup in a DVD before
encrypting it. There are lot of data recovery software available. But I'm not sure if
those software can recover files that are encrypted. Maybe they may recover files
that are encrypted, that you won't understand. The chances are really slim.

you need either the certificate from the old user a/c or atleast the UID and Machine ID form the old installation to work around this prob...

I think u can't do much abt unless you have certificate of userid from old installation. Creating the a newuser under same name doesnot generate same secutrity id. I don't know any applications for recovering data from it though..

Wont work either.. The certificats are completely random! So maybe if u install windows kazillion times, you may get the same certificate :p :D

If I have a text backup of the Certificate number can that help? Should I start looking?
