I have a client that had to rebuild his PC and went from XP to Windows 7,  however he had encrypted files (Windows Encription) on an USB drive I didn't know about. I don't think he has a backup cert. Is there anyway to recover these files? I have the USB drive with me.

Unlikely, the EFS Public and Private Keys would have been stored in the XP filesystem.  Even though they know their public key without the pair the files cannot be decrypted.

I was afraid of that, you confirmed everything else I have been reading.
