关闭 APIPA

I just did this on Win7 Professional and it works. I tested it before and after making the change.

1. Use Registry Editor to create the following registry key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
2. Add the following value to this key:
Value name: IPAutoconfigurationEnabled

Value type: REG_DWORD

Value in hexadecimal: 0 (A value of 0 disables APIPA support on this computer) 

NOTE:
 If the IPAutoconfigurationEnabled entry is not present, a default value
 of 1 is assumed, which indicates that APIPA is enabled.
3. After you make this change, restart your computer.
