Whenever security and usability/backwards compatibility (even with serious mistakes) clash at Microsoft, security loses.
This is the company that hooked up Windows 98 and even XP to the internet with no security model, administrator logins for everyone, and no firewall.
Then waited until the news was actually reporting on what a worm farm Windows had become and how once you had it connected to the internet, it was a matter of about 3 minutes before it was infected.
This attitude at Microsoft has only changed to the extent that there's security theater now and they pay off the fake news to say "PC problem" and everything open source is "Linux".
