If the key has any values, it means one or more files have been flagged for a rename. The flagging of the files occurs after a system restart or reboot has been performed. Normally, this action does not pose a problem for the ePO upgrade. The the ePO upgrade might fail if either of the following conditions is met:

• The file in question is one that ePO needs to replace.
  Or
• The file exists within a folder that ePO needs to replace or rename.
