said by StuartMW:+1 This is the only way to go! Certainly don't want updates occurring when you are in the middle of something.
I don't let any software update automatically. All automatic updates are disabled.
I prefer to get, and keep, the full installers for all software (in case of re-install, new-install etc) and I get them when new versions are announced. I also prefer to update on my schedule (and knowledge) vs the vendors (and updaters).
