Notes

Different administrative credentials are required to perform this procedure, depending on the environment in which you add or delete a designated file type:
- If you add or delete a designated file type for your local computer: To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
- If you add or delete a designated file type for a computer that is joined to a domain: To perform this procedure, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.

It may be necessary to create a new software restriction policy setting for the Group Policy object (GPO) if you have not already done so. For information about how to create new software restriction policies, see Related Topics.
The list of designated file types is shared by all rules for both Computer Configuration and User Configuration for a GPO.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
