Enable administrative shares in Windows Vista & Windows 7

The administrative shares are disabled in Windows Vista & Windows 7 by default. In order to access your drives remotely, addressing them like \\hostname\C$ or \\hostname\D$, you have to add a key to the policy hive in the registry:

• run regedit.exe (in Administrator mode)
• navigate to
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system
  
  
• create a new DWORD value and name it LocalAccountTokenFilterPolicy
• set the value of LocalAccountTokenFilterPolicy to 1
• reboot and try to access your administrativ shares (e.g. \\localhost\c$)

That's it!
