0Enable access to the c$ share on Windows 7 and newer

I have a range of HTPCs run­ning win­dows around the house, which I largely admin­is­ter via remote desktop. Occa­sion­ally it is use­ful to access the root of the C drive remotely. Win­dows has always catered for this by cre­at­ing some default admin­is­trat­ive shares, which are hid­den. The C drive is accessed via \\remote-pc\c$ for example. In win­dows 7 I found I was­n’t able to access these shares by default as they have been restric­ted (under­stand­ably). I needed a way to make them access­ible again.

The fix turned out to be rel­at­ively simple. A simple registry tweak did the trick.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"LocalAccountTokenFilterPolicy"=dword:00000001
