Ok, well how do I know you knew that? You didn't say anything about it your first post.
You do what I stated in the first place. Either use a third party theme, or modify Windows system files, components.
Look into "Resource Hacker" and search around for "Windows command bar color customize", or "Menu bar color change". There is no quick manual one-step way to do it, unless you find a program to do it for you.
