What did you use to encrypt them?

The EFS certificate files can be found in "C:\Documents and Settings\Application Data\Microsoft\SystemCertificates\My\Certificates".

If you have the Documents and Settings directory from the old windows set up, or you have a backup of the certificates. They are stored each in one file, named by thumbprint, with no extension. ANother way to recover them may be to roll back the windows update if you still have windows .old or search the windows .old for the keys.

If you do manage to locate them then try : click here

but without the keys there is almost no chance of recovering the data.

"C:\Documents and Settings\Application Data\Microsoft\SystemCertificates\My\Certificates".

substitute your user name for MY

E.G. "C:\Documents and Settings\Application Data\Microsoft\SystemCertificates\Username\Certificates".
