Critical Updates???


I see often the mention of some Windows updates on Patch Tuesday as being critical.
In the twelve months I have had this computer I have had optional, recommended and important updates but never critical updates.
It ain't the end of the world, but I am curious if there is a difference depending on where you are in the world with regard to those terms.
