A bug.

If setup.exe stores those paths, then its a bug there.

You could have tested that easily, on a cmd window:


C:\Users\reneb>dir \\?\C:\
  Volume in drive \\?\C: is OS
  Volume Serial Number is 922E-C431

  Directory of \\?\C:

12/09/2019  02:52 PM    <DIR>          Apps
01/04/2020  03:11 PM    <DIR>          Boot
04/05/2020  12:12 PM    <DIR>          cygwin64

C:\Users\reneb>dir \?\C:\
