yes unfortunately that is a requirement. One would hope MS would come up with a better solution. Fortunately, for my organization at least, is that we're somewhat small and the workaround of saving a Pdf and then printing is acceptable for my user community until the patches are distributed. Within a day or so we are able to have approx 90% of our machines patched, so the majority of them never notice.

You may want to work with your systems management/patch management folks and see if they have the availability to use Wake on Lan to wake up the workstations during non-production hours to ensure patch delivery overnight while the workstations are not in use. Or you can ask them to set up a larger number of repositories and to push that particular update separate from your monthly update cycle. Since it's not very large, and it doesn't require a reboot, it should be easy to distribute the same day you patch your servers.
