While the theory of Automatic Updates is fine in theory, the practical application of this option has some nasty repercussions. Say you’ve been working on an Excel spreadsheet for two hours without a backup and NOW your computer decides is a good time to do an Automatic Update – not good!
You would think Windows would give you an option to close down and save the work you’re got open, but it doesn’t.
The best way out of this dilemma is to to turn off Automatic Updates and change it “Download updates but let me choose whether (and when) to install them. You do all of this in Control Panel – Windows Updates – Change Settings.
Now this doesn’t mean you should never do the updates, you should, but it does allow you to say when the updates should take place.
