Attention: This wizard may only provide English version. However, other language versions of Windows also provide automatic repair functionality.
Attention: If you are using a computer that does not have this problem, you can save the auto Repair feature to a flash drive or CD, and then run the feature on the computer that has the problem.

Important Notes: This section, method, or task contains steps for how to modify the registry. However, there may be serious problems with incorrect registry modifications. Therefore, be sure to follow these steps strictly. For further protection, back up the registry before you modify it. This allows you to restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows
To disable certain IPV6 components yourself, 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 "item.
Attention: If the "disabledcomponents" item does not exist, you must create this item. To do this, follow these steps: On the Edit menu, point to New, and then click DWORD (32-bit) value. Type disabledcomponents, and then press Enter. Double-click "DisabledComponents". In the value data:
field, type any of the following values to configure the IPV6 protocol to the desired state, and then click OK: Type 0 To enable all IPV6 components (Windows default settings) type 0xFFFFFFFF To disable all IPV6 components (except IPV6 loopback interface). This value also configures Windows Vista to use Internet Protocol version 4 (IPV4) in the prefix policy, instead of using IPV6. Type 0x20 to use IPv4 in the prefix policy, instead of using IPV6. Type 0x10 to disable the native IPV6 interface. Type 0x01 to disable all tunneling IPV6 interfaces. Type 0x11 to disable all IPV6 interfaces (except the IPV6 loopback interface).
Advanced Steps
Important matters: The following steps apply only to advanced users.
to use IPV6 instead of IPv4 in the prefix policy, follow these steps:Locate the current numeric data for the disabledcomponents. Change the data to
Binary data. The data becomes the 6th digit of the 32-bit binary data to find the data, and then sets it to 0. Do not modify any other bits. For example, if the current data is 11111111111111111111111111111111, the new data should be 111111111111111111111111111
011111. Change the data from binary to 16. Sets the hexadecimal value to the new numeric data for the disabledcomponents.
to enable the native IPV6 interface, follow these steps:Locate the current numeric data for the disabledcomponents. Change the data to
Binary data. The data becomes the 5th digit of the 32-bit binary data to find the data, and then sets it to 0. Do not modify any other bits. For example, if the source data is 11111111111111111111111111111111, the new data should be 111111111111111111111111111
01111. Change the data from binary to 16. Sets the hexadecimal value to the new numeric data for the disabledcomponents.
to enable all tunneling IPV6 interfaces, follow these steps:Locate the current numeric data for the disabledcomponents. Change the data to
Binary data. The data becomes the 1th digit of the 32-bit binary data to find the data, and then sets it to 0. Do not modify any other bits. For example, if the source data is 11111111111111111111111111111111, the new data should be 1111111111111111111111111111111
0。 Change the data from binary to 16. Sets the hexadecimal value to the new numeric data for the disabledcomponents.
to enable all IPV6 interfaces except the IPV6 loopback interface, follow these steps:Locate the current numeric data for the disabledcomponents.
