"critical" updates slow netbook..Packard Bell dot..Windows 7 starter

The problem I report here I have found with every computer I have owned.

I have set my computer to "check for updates but let me choose whether to install them" and do not download them.

Regardless of this setting I notice (often within days) that my computer is much slower than usual and when I check via the "restore my computer to an earlier time" facility I can see that there are downloads of "critical" updates. I usually pick a point before the update and restore - this sets my computer back to running at a decent speed.- (these "critical" updates are not shown on the "installed updates" page which is why I check via the restore facility).

What is the problem here and WHY does my computer download these "critical" updates ?

What is the point of having various setting regarding downloading updates if they are downloaded anyway ?

I have noticed this problem of "critical" updates and speed on every computer I have ever used ( all with differing amounts of memory/cpu/etc etc).

Why is this ?

There are some updates which are regarded as of overriding importance, and which ignore the settings - however, they are very few, and generally do not lead to any slowing of the system except at the first boot after install.
Exactly which updates are you talking about?
