I'd say that it's a threat that's fast diminishing, given the number of people that I come across these days who are conversant with MS-DOS 
But to do certain things on Windows, it may be necessary to access Dos.
It's OK, thanks for the link - very interesting
Realistically, it does not pose much of a threat if no one has managed to spot it in 17 years. 
...Not the most critical problem.

As I said....see emboldened text...
Nevertheless an exploit....
Nick asked a question I just supplied an answer.....
Microsoft need to come out with a proper ALL new O/S & stop thinking "We must make sure it works with all previous MS O/S`s", but they won`t....
But IE is still vulnerable & will remain so until MS get off their backsides & fix it.....
