Sometimes when my Win 7 machine has programs that crashed, maybe Firefox, or IE, I would like to shut down the computer without installing any Windows update. That's because I worry that if IE or Firefox crashed, the system is not in a very stable state, so I would rather install the update later.

But it seems I only have 2 choices:

1) Shut Down and it always will do any Update
2) Restart, and no update is done

(these are 2 choices among the shut down / log off option)

So is there a way to Shut Down without doing the Update? Or must I restart first, and then do the Updates, and then Shut Down?
