A while ago, I asked [this question](http://superuser.com/questions/660409/what-happens-if-i-install-a-virtual-machine-additions-package-on-a-host-pc), which got marked as a duplicate. It originally contained two questions, of which the first was answered by both this question's and the target question's answers. However, the second was never answered. I have edited the question to only contain the second. Can it be reopened and answered?
