CTLInfo can examine the full list of all windows root certificates.

Windows checks for trusted CTL updates once a week while untrusted CTL is checked once a day. A CTL is a predefined list of items signed by a trusted entity. A CTL is a list of hashes of certificates or a list of file names. All the items in the list are authenticated and approved by a trusted signing entity.

Windows currently trusts 374 root certificates, but the Certificate Manager only displays a subset. Enter CTLInfo.

CTLInfo is portable and once executed provides shows all your Trusted and Untrusted CTL information side-by-side:
