I created a LOCAL ADMIN account. It only shows up if I want to make changes to it. No folder and a search of the system drive reveals nothing.
I click on Control panel>User Account and only my MS account is displayed. I then click on "Manage another Account" and both accounts are displayed.
It seems that MS wants to be the "King on the Hill'.
Have you actually logged into the newly created local account? There won't be much evidence of its existence until you actually log into it. Right click on the start icon and then under the power options will be the option to sign out. You can switch users and log into the new local account created.
