    If the your encryption certificates and keys were not backed up
before the user deletion/creation caused by the reinstallation, and
the workstation isn't part of a domain, I'm afraid that those files
are gone, for all practical purposes. Encryption works well and
there is no "back door" or hack to access the files. (Wouldn't be much
point to EFS if it were vulnerable.)
