Disable IPv6

To disable certain IPv6 components in Windows Vista, follow these steps:

• Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list.
• In the User Account Control dialog box, click Continue.
• In Registry Editor, locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
• Double-click DisabledComponents to modify the DisabledComponents entry.

Note:- If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:

• In the Edit menu, point to New, and then click DWORD (32-bit) Value.
• Type DisabledComponents, and then press ENTER.
• Double-click DisabledComponents.

Type any one of the following values to configure the IPv6 protocol, and then click OK:

• Type 0 to enable all IPv6 components. Note The value "0" is the default setting.
• Type 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.
• Type 0x20 to use IPv4 instead of IPv6 in prefix policies.
• Type 0x10 to disable native IPv6 interfaces.
• Type 0x01 to disable all tunnel IPv6 interfaces.
• Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.

Now You must restart your computer for these changes to take affect.
