  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
