    I tried Step 1 (regedit) and it seems to have worked. Thanks for making an easy to read guide with pictures. Also the comments on this site are very helpful. I'll let you know if I have any further problems, but for now Step 1 (regedit) has my internet working again.

    Thanks VERY much — that particular glitch had bedeviled a Win7Ult desktop of mine for months, and none of the other so-called "expert" websites (including MS) proved to be relevant or worthwhile, but this fix worked!

      Well, it did work just fine, but the problem had resurfaced when I checked Device Manager earlier today so I had to perform the registry edit again. After rebooting, the flag and error code was gone so for now all is okay. I'll keep checking periodically, but there may be something else at work in producing the intermittent failure of that particular adapter's functioning.

      A further update — I discovered that two services on that machine ('Peer Networking Grouping' and 'Peer Name Resolution Protocol') were not started, and in one of the many other threads on this issue these two services were identified as potential accessory culprits for the problem. So, I've changed them both from "manual" to "automatic" and rebooted — there are no flags in Device Manager, and I'll monitor it periodically and see if the combination of fixes has finally resolved the problem for good.

    You are a king!
    I spent more than 4 hours in trying to solve this nagging problem.
    Most of my effort focused on shutting down and restart computer and router, but nothing really helped.
    Out of desperation I contacted technical support center of my Internet provider, and after millions tests, I was told that my network card is burned and that I should contact a computer technician to take care of my computer.
    Frustrated and furious, I decided to try and find a mention of to this problem on the net, and so I got your explanation.
    A very simply and detailed explanation of which accompanied me step by step finally to a complete solution of the problem.
    Thus I wanted to thank you so heartily and say well done!
    You helped me very much, Shmulik.

    Hi! I logged into the administrative account. I managed to continue after setting the value to 0 and selecting OK. Afterwards, I restarted the computer, went to Computer Management, and selected show hidden devices. I noticed the Microsoft Teredo Tunneling Adapter disappeared. The only thing I see now is Teredo Tunbeling Pseudo-Interface. That's it. Did I make a mistake? What should I do? Thank you.

    Hi! I followed your steps perfectly to the step where I set the value at zero and select OK. Once I clicked OK, a tab appeared named 'Error Editing Value'. Then inside the tab it said "Cannot edit DisabledComponents: Error writing the value's new contents." I don't know what the problem is. I'm logged onto the second user (the non-administrative one but that doesn't seem to be the problem). What am I suppose to do? Can I fix this?

I called Comcast, & a guy there said reboot your modem, & then reboot your PC, and dot dot dot viole (can't put that thingie over the e-sorry), I'm back on the net. Apparently, a simple solution for a simple mind! Hope it continues to work. If not, I'll review all the above.

    I just want to add my solution here in case anyone else has this problem. I fixed it extremely easily by simply looking at the registry of a working win 7 laptop. Just delete the registry key in the photos in step 1 named DisabledComponents. In my registry, the EnableICSIPv6 registry key was absent altogether, so I created it by right clicking in the white space and clicking DWORD. Then you rename it to EnableICSIPv6, enter 1 as the value and click the Hexadecimal radio button. The exclamation on the Teredo Tunneling device is gone and there appear to be no issues.

    Lakonst,

    Before seeing you last reply instructions, I tried all three steps once more and found that after restarting the computer, the registry value was no longer auto changing itself, but that also the Teredo adapter was not installed. I reinstalled the adapter AGAIN, and restarted. The registry value mystically has stopped changing itself, and the adapter is installed and working. After a week of restarts, it has not malfunctioned again. So, thanks! No idea what fixed it, but all's well.

    Cheers!

      Okay… I was mislead. It appeared to work for that day, but today, when I turned the PC back on, the adapter once again is giving the Code 10 (cannot start). So, me donating above through PayPal was a waste. What gives? Why is this adapter suddenly not working?

        @Link: I' m really sorry for your problem. Do you have any firewall program installed? If, so please uninstall it. (like AVG or Zone Alarm? specially in ZA your have to Enable IPv6 checkbox in Firewall).
        1. Make sure that all your drivers are updated.
        2. Make sure that the IPv6 is enabled in network properties.
        3. Set the value to 0 in registry and then restart your computer. (do not uninstall/re-install teredo) If the problem persists then…
        4. Give these commands (in order, as Admin) and then restart your computer:
        netsh
        int teredo
        set state disabled
        int ipv6

          I had replied with more information, but it seems y'all deleted it.

          The only security programs I have installed are the same one's I've been using for years: Window's Firewall, Avast Free Antivirus, and Malwarebytes Anti-Exploit Free. I have checked through and through them looking for anything dealing with IPv6 options and there is nothing restricting listed.

          1. My drivers are all up to date, as always, on both computers on my network.
          2. IPv6 is enabled on both computers.
          3. I have done that step multiple times. It always works for ONE reboot. After the computer is again restarted, the registry value automatically changes back to 8e, and, subsequently, the Teredo adapter gives a code 10.
          4. I have also done this to no success.

          I also cannot connect to a Homegroup with either computer. I can start one on both, but neither shows that there is a Homegroup on the network… even though I can see both computers and peak into their folders from the other computer. They are both on the same "Home" network. They are both on the same Workgroup.

          I have a Netgear Nighthawk R7000 802.11ac router and I've also checked through that for anything reguarding IPv6… nothing is restricted. I've restored everything to defaults. I tried setting various options on and off… I've spent at least 6 hours trying to figure out what's gone wrong and why that registry value keeps auto-changing itself back to 8e from 0.

          I cannot think of anything I've done recently, since when I noticed the device wasn't starting, that I've changed from my normal habits. I can't think of any new programs I've tried out.

          Everything I find through Google is from around 2011 to 2013, and the instructions to fix it are the same as listed here, or to simply disable the adapter, as apparently, it's not needed.

          Thanks for the response.

            OK then. Let’s find which process modifies the registry.
            1. Open an elevated command prompt and run the following command:
            auditpol /set /subcategory:"Registry" /success:enable
            2. Then Open Registry Editor and navigate to this key:
            HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters
            3. Select the “DisabledComponents” key.
            4. From menu choose: Edit > Permissions
            5. Choose “Advanced”.
            7. Choose the "Auditing" tab
            8. Click “Add”
            9. Type “Administrators” on the box and click OK.
            10. Click the “Set Value” checkbox at “Successful" column and press OK.
            11. Apply settings and press OK to Exit.
            12. Now change the “DisabledComponents” value to 0 and select OK.
            13. Close Registry Editor and restart your computer.
            After Restart:
            1. Open Event Viewer > Security
            2. Select “Registry” line(s) (Task Category) to find out which process (Process Information) modifies the “DisabledComponents” registry value.
            Good luck!
