How to share C$?

I would like to share the C drive of my second system, so I can access its entire disk from my main computer. There is a C$ share already defined which I would like to make accessible (as it was possible under Win XP).

But when I try to do that under Win7 I always only get the message that "This has been shared for administrative purposes [beats me what that purpose may be, but so be it]. The share permissions and file security can not be set".

Why can I under Windows 7 no longer set the sharing properties of "C$"? Not even as Administrator! What is this share then good for?

You can't change the share permissions of C$ ever, not on any version of windows. It's used for the backup service and some other internal things. Only system processes have acess to it.

Just create a new "C" share and set your own permissions and leave the C$ share alone :)
