If you get an error while trying to access the Windows hidden C share (C$):

net use \\localhost\c$

System error 53 has occurred.

The network path was not found.

A simple thing is just to make sure your TCP/IP NetBIOS Helper and Server services are running (Start-Run, services.msc) and try again:

net use \\localhost\c$

The command completed successfully.

Of course, your user must be either an administrator or be part of the administrator group.

If it still fails, manually edit the registry (Start-Run, regedit). Browse to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System 

and create a new DWORD value LocalAccountTokenFilterPolicy set to 1
