Low awareness of security and stability among Microsoft developers

Although the situation is changing, it's evident that Microsoft's NT developers are still working from the premise that a single user will use a single dedicated computer. This mindset assumes that if a machine crashes or is compromised, that failure will affect only one user and one computer. The one-user, one-machine scenario used to fit word processors and spreadsheets, but the nature of enterprise computing has changed drastically. At least in situations in which security is concerned, we're not in Kansas anymore.
