Can I see which Certification Authorities have their own Trusted CA root present in browsers?
Yes. Your browser contains a Trusted CA root certificate store. You can access this by opening Internet Explorer, then go to Tools, select Internet Options, select the Content tab, click Certificates, select the Trusted Root Certification Authorities tab. You will then see a dialog box presenting a list of all Certification Authorities who own their own Trusted CA roots (you can examine the root certificate by double clicking it).
