If your encryption certificates and keys were not backed up before
the reinstallation, and the workstation isn't part of a domain (whose
Administrator might act as the designated recovery agent), 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 easily by-passed.)
