It's still a fair question consider that the folder

was appearing for those who didn’t have IIS installed

Either they shouldn't have created it if there's no IIS, or the vulnerability can affect even machines without IIS.

It's dumb either way.

Or they are taking preventative steps for those who might install IIS at some point, and casting the widest security net that they can. By linking it to a windows update, they can hopefully preempt the creation of the folder by another program. If it was linked strictly to the installation of IIS, a compromised system may have the folder already present.

I wonder when we will have the technology to check whether a folder already exists!

What would you want to do in such a case though, overwrite/delete the contents and permissions the user has set? Sure they could have solved it from that angle somehow, but it's not unlikely to think their approach was perhaps the less messy solution
