Enable administrative shares on Windows 7

Add this registry key. This is formatted as a reg key, so you can save it to a file “localaccount.reg” and just run it from the shell.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"LocalAccountTokenFilterPolicy"=dword:00000001

This enables shares of the form C$, D$ etc. This assumes that “File and Printer Sharing” is enabled (you’ll find this in the Control Panel : Network and Internet : Network and Sharing Center : Advanced sharing settings”).
