Windows has the option to automatically dial your Internet Service Provider (ISP) to establish an Internet connection. This option can be controlled using this tweak.
Open your registry and find the key below.
Create a new binary value named “EnableAutodial”, and set the new value to equal “01 00 00 00” to enable autodial or “00 00 00 00” to disable it.
Note: This restriction can be used either on a user by user basis by adding it to HKEY_CURRENT_USER or on a computer wide basis by adding it to HKEY_LOCAL_MACHINE.
Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
Value Name: EnableAutodial
Data Type: REG_BINARY
Data: 00 00 00 00 = disabled, 01 00 00 00 = enabled
