you can set "Active Hours". These are hours that the machine is not supposed to try and force an update. Mine was set from 8am to 5pm so obviously that didn't work this past Tuesday. I changed it from 6am to 11pm in hopes this will work. Didn't see anything about changing dates or even days of the week.
Chris, Setting active hours will only tell Windows it can't restart during those hours and, apparently, it will not restart without asking you.
I think (I am trying it now), you have to go to Advanced options below that setting to set pause. This pauses updates for 35 days. If you decide to allow updates, you cannot set it again until after the new updates. Where they get 35 days, I don't know. Seems like a bit long. I guess one has to choose between security and usability or another way of putting it: Security vs If it ain't broke down update it.
