For all of my office Windows desktop systems the users are setup as
administrative users, so I don't have any non-admin users to test what I
think you are asking. robynr is an admin user on the Win10 box below.
But as shown below I list the shares on a new Win10 box, then access the
Users share, then try accessing the ADMIN$ share with the same
credentials. I get the same results when trying the C$ share as with
the ADMIN$ share shown below. But I am not sure if this is where you
were going with your question.

In the case of my own desktop, jeffb is also setup as the administrative
user on the Win7 box. Using the same procedures as above I can connect
to the Users share. But in this case I can also connect to the C$
share. I also tested the F$ and G$ shares listed and could connect and
list their directories also. I could also connect to the IPC$ share,
but then got an NT_STATUS_ACCESS_DENIED response when trying to get a
directory listing.

I did find this notation in my Win7 box help dialog regarding using
Advanced Sharing.
Note
You can't share the root of a drive with a dollar sign following the
drive letter as in versions of Windows earlier than Windows Vista. For
example, you can't share the root of your C drive as "C$," but you can
share it as "C" or any other name.
I noticed that I have one Win7 box in the office that I must have set up
an independent "C" share, as that is what BackupPC is using to access
and backup that box. I still can't find anything different yet in the
network settings of my own desktop box that would indicate that it would
override the note indicating that you can't share the C$ share. So I
don't know why my Win7 desktop can share C$ when none of the other
Windows boxes in the office can.
