Microsoft's security reputation prior to the recent (5ish years?) failures was largely built up on top of the work stemming from the Trustworthy Computing memo.

Satya Nadella in 2024: "If you’re faced with the tradeoff between security and another priority, your answer is clear: Do security."
Microsoft in 2024: Run this software on your computer so we can take a screenshot of everything you do, index it and we promise Security is still, and have always been, the priority. And yes, we do store data unencrypted on your disk, why are you asking?
But don't worry, you need to be an administrator to open the file. What? your average person daily drives an administrator account? How should we have known that???
