Refer to the Product Guide for EEPC 7.0.1, http://kc.mcafee.com/resources/sites/MCAFEE/content/live/PRODUCT_DOCUMENTATION/2 4000/PD24423/en_US/eepc_701_product_guide_en_us.pdf
Page 29 and 30 describe how to de-crypt the computer. You must de-select the "Enable Policy" in the Product Settings policy. Next time the computer communicates with the EPO server, it will get the updated policy, and begin decrypting the drives. This can take several hours. Once the decryption is done, you can uninstall the EEPC and EEAgent software using an uninstall task from the EPO server.
