Several Windows editions were awarded the Common Criteria EAL 4 certification..... "Common Criteria"...? You have most likely heard of the US TCSEC (Trusted Computer System Evaluation Criteria) or the European ITSEC evaluation criteria.
However the "Common Criteria", based on ISO 15408, are the 1st truly international approach to evaluating vendor security products. EAL is the abbreviation for "Evaluation Assurance Level" and each EAL level describes a certain set of assurance requirements witrh regard to security functionality.

Keep in mind, this certification is about security features, you still need to implement those features correctly no matter wether it's EAL 4, EAL 3 or whatever...
