“At base the Microsoft products all go back to a core that is
built on the MS-DOS concept of a single task, on a single computer
for a single user. There is little need to be concerned about
security with such a design. This is a fine concept if one never
attempts to use such a system for anything other than a single
task, on a single computer for a single user. But that is not what
Microsoft has done. The Microsoft products simply kept that single
user, single computer base technology and added on multi-tasking
(Running many programs at one time.) and networking (Connecting
many computers together for sharing data, printers and so on.)”
