Some initial clarification: the LaunchProtected key is, as is the installation as it is, tied to a requirement from Microsoft. Plus the service is tied to the Early Launch AntiMalware (ELAM) driver, which again is a requirement.

We're not "taking control" of Security Center, we're doing what is expected from us by Microsoft, which is adding Spybot there. For Anti-Malware only in the Free Edition, for AM and AV in the paid editions.

So one very important thing to this discussion: please mention if you're referring to the Free Edition or a paid one.
