You have Windows 10 installation media, such as an iso file that is downloaded from MSDN, that is not in the en-US language (for example, fr-CA or en-GB). On this media, the junction points might be missing in the Default User profile. Because of this issue, any user profiles in this system that are created in the future will not have these junction points.
For example, when this issue occurs, you see the following output when you run dir /AL under the user profile folder:
Microsoft Windows [version 10.0.15063]
(c) Microsoft Corporation, 2017. Tous droits réservés.
C:\Users\user>dir /AL
Le volume dans le lecteur C n'a pas de nom.
Le numéro de série du volume est 14A6-898C
Répertoire de C:\Users\user
Fichier introuvable
By contrast, here is an example of output if the junction points exist:
C:\Users\user>dir /AL
Volume in drive C is OS
Volume Serial Number is C82E-3889
Directory of C:\Users\user
