Thank you in advance for any guidance!

Vista Ultimate (32bit SP1) system is corrupted enough to not boot but
accessing the HD from another system seems to have virtually
everything intact. One single file was encrypted using EFS on the
system. I'm wondering if there is a way to manually transfer over the
certificate/s from the old hard drive into the new system.

I am aware of ElcomSoft's Advanced EFS Data Recovery software but the
problem is that the file that is encrypted is actually another file
that is encrypted using another encrypted software (basically the file
is encrypted twice, the outside container is Vista EFS and the inside
container is TrueCrypt). So I can't see if ElcomSoft's Advanced EFS
Data Recovery software will work in the demo/trial as I still have yet
another step to proceed to decrypt the file in TrueCrypt.

I've found manual recovery processes for XP ( http://www.beginningtoseethelight.org/efsrecovery/
)but the registry structure is different enough in Vista that I can't
find the same place in Vista.

Does anyone know the comparable location in Vista for hklm\sam\sam
\domains\account\users\%usernumbers% (which is XP)?

Any other ideas?
