    I had most of my hard drive encrypted with the advanced properties encryption option. Windows told me my user password had expired, so I changes it. Upon doing this, all the encrypted files were no longer accessible, or decryptable through the advanced properties option.

    I think that when I changed the password, Windows changed the encryption keys it uses, without reencryping the files to use the new keys.

    Anyone have any ideas on how to decrypt these files?
    Let me know if you need any additional information.

    I would say that you have to take take ownership. Go to How To Take Ownership to read how its done.

    I was able to change the ownership of the file around, but I was still unable to decrypt the files. The access denied message still comes up when I try to decrypt or open the file.

    Hmm... In the "Known Limitations" of EFS there is listed: The program can decrypt protected files only if encryption keys (at least, some of them) are still exist in the system and have not been tampered.

    Sounds to me like you need that key floppy that you should have made when you encrypted those files...
