Re: Still baffled
"what MS subsequently did would leave their users wide open to attack"
You mean like how the created user profile for users on a home installation of XP had admin rights by default, and how the restricted user profile was so restricted it was near useless for many (you couldn't even change the time FFS). There was, I believe, a tool to tweak what rights users had, in the enterprise version...
It was pretty much a wide open door back then, just marginally less open than Win32 machines.
