That's right. I only became aware of it because one of the computers is getting low on HDD space, so I was trying to get rid of excess stuff. When I saw it, I was wondering what it was doing there. Then I realized it was part of the kid's web development software for a school project.
Then I was looking up local host ports and realized that my Bentley workshop manual software for Volkswagen also installed SQL on my computer. So you never know what applications are dependent on it until you check.
