Kind of makes you want to switch to a less targeted OS?
Not really..................you need an authenticated login and physical access from what I can see?

Hell! I am looking at a CD on my desk that will reset the admin password from bootup................no login required.

I am still of the opinion that if someone has unrestricted physical access you are as good as owned.

Anyway, it took 17 years to find it..............hardly earth shattering?
