What else did you want them to do to prove they were taking the exploit seriously?
Well I'm not writing a book for you, and someone else already covered an example.
Why don't you tell me the answer to your questions.
This isn't a test. What is this? High school?
The fact that you're being acutely defensive suggests to me that you just wanted to engage in some good old fashioned Microsoft bashing with nothing constructive to add in the safety of slashdot.
As far as how I would answer my own question, based on my original assertion that they have already taken it seriously; nothing.
However, since you suggested that they have not taken the exploit seriously enough, I wondered how exactly our positions differed (since I can't read your mind) and what exactly they would have to do so that you and I agreed that they were taking it seriously enough.
Remember, I already think they are taking it seriously enough based on the release of patches back to win 7 and a workaround given for non-patched machines, so my answer is "nothing", but that clearly can't be your answer because otherwise we'd agree.
