MS took away a great deal of the Group Policy functionality from Pro. They did it to force organizations to pay the much higher price of Enterprise versions.

Well that's just great, I don't use the business features and this has kicked in It never demanded this when I clean installed RS2 either, it let me do a 4 digit pin.
Fixed and FU Microsoft. For anyone else trying to find a way around this. Save the following as a registry file and reboot after merging it. Also rar with reg file attached. Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork\PINComplexity] "Expiration"=dword:00000000 "SpecialCharacters"=dword:00000000 "MinimumPINLength"=dword:00000004 "History"=dword:00000000 "UppercaseLetters"=dword:00000000 "Digits"=dword:00000000 "MaximumPINLength"=dword:00000008
