Can not do restore either. Real bad
Are you SURE you're targeting the right update to uninstall? It may not let you uninstall any update, but this one should be uninstallable.
If you're feeling lucky, try some of the suggestions you get when you google "manually uninstall kb update", make sure you don't follow any instructions not meant for your version of Windows.
At the very least, backup your virtual machines ASAP. If you have another system available or can install one, you could use them there for the time being.
