+         * The `extensionHardening` Windows registry key affects this API. The file extension defined by the `base64File` param must match the real file type of the inserted file. If `extensionHardening` is set to deny mismatches and the file extension does not match the real file type, this API throws the following error: "This operation is not allowed due to the extension hardening policy."
