Or it could just be a clone of macOS Gatekeeper, which is a signature check. Could be Microsoft used an “or” after “blocks untrusted…” instead of an “and”, and a sig check is all they’re doing. If that’s the case, Gatekeeper can be a minor inconvenience but doesn’t block installation if one knows to right-click the icon.
