Edit: I have since disavowed this instance
Computers mostly don't force software updates on you, unless you tell them to. (Caveat: IT routinely forces updates on people.) Find the setting where you specifically asked the machine to keep itself updated, and turn it off. If you can't find it, throw the machine away and get a better one where you can be in control:-P. This concludes my sermon for today, I hope you all have some Happy Holidays!:-P
