Signing is a useful measure. But not by itself. There are several harder admissions to be made. The security business is very lucrative ambulance-chasing. A business-grade OS needs high-confidence evaluation and design. mWindows cannot be safe while being all things to all users, with backward-compatability extending three decades. It may be time to split the product into more than just artificial marketing tiers. Rewrite the OS in a safer language. I won't pick one, but Microsoft is large and sufficiently profitable to know what to do and how to do it. mWindows 11 should not just be a change of curtains and doilies.
