Firstly they say your main audio computer should not be on the net and that is always good advice. I have also seen it said that you should turn Automatic Updates Off. It is yet another task running in the background that you don't need.
If you do feel like updating your OS you should do the research and really find out what the update is actually for and in most cases it will have nothing to do with audio and will give you no benefits. It will often be for internet security issues because as we know Microsoft make the worst OS for internet security and will continue to do so I am sure.
I have had a computer for years not being (OS) updated and it has never failed at doing audio production which is what I do.
