Use Regedit to Create LocalAccountTokenFilterPolicy Value
Type Regedit in the Search dialog box, best right-click the executable and 'Run as administrator'.
Once Regedit launches navigate to this path:
HKLM\SOFTWARE\Microsoft\Windows
CurrentVersion\Policies\System (See screenshot below)
Windows 8 Registry Editor
Once you ar at this folder in the registry:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Notes: The text book says create a new DWORD value called LocalAccountTokenFilterPolicy
What I did was create a QWORD (64-bit) called LocalAccountTokenFilterPolicy, that worked for me when the DWORD would not allow access to my 64-bit machine.
In either case, set the value to numeric 1 (meaning on), remember to click OK.
