If the attacker gets full administrator-level access on your machine,
there are a gazillion ways the attacker can prevent other admins from
logging on. This patch can't prevent that. It sounds like this patch
is trying to solve a fundamentally unsolveable problem.

A useful slogan: "Don't forbid what you cannot prevent."
