please,

what is "enumerate"?

i am trying to understand a wireless routine here that according to a
Registry activity trace does whats shown below (well, part of it is
shown below).

My question is:

what does the "EnumerateValue" do?
and why does it "enumerate" the same thing twice before setting a
value - for example in lines 11 and 12 before setting a value in line
13.

i can find lots of info on the internet about HOW to enumerate keys,
etc but nobody explains what "to enumerate" means :(

tIA for any explanation you could give me
