Can I have a question closed, or should I move it to community wiki, or...what's the best practice?

Specifically https://serverfault.com/questions/355020/windows-update-not-working-on-windows-server-2008-r2, simply because there is no way to ever verify now if an answer is correct or not.

I don't want it to count against my acceptance ratio, since no one can technically ever "answer" the question now that I've had Microsoft support fix the issue. But on the other hand, I compiled a lot of steps together that aren't already compiled in one spot on the net, and motobói put a response with brand new content that after days of research, I hadn't ran cross before. It could be very helpful to the next person, so I don't want to just remove/delete the question either, even if no verifiable answer can be given at this point.
