Method Four: Through Registry Editor
This is not the method that we would recommend until all these methods above fail to work. If that is your situation, here we go:
- Using Windows + R, open your Run command
- Input regedit and then press Enter to open the Registry Editor.
Note: Because any error made here can cause some errors, what you want to do is to back up the registry by following these steps:
- In the Registry Editor, simply go to File and click on it or right-click on the computer icon at the top left corner of the first pane.
- Select export
- Select where you want the file to be saved and click Save.
Once you experience any problem, you can follow the same steps and select Import rather than Export.
Now you can continue with these steps:
- Copy this and paste in the address bar of the Registry editor and Navigate to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters or simply double click on all these from the first pane: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > Tcpip6 > Parameters
- On the right Pane, look for the entry with Disabled Components
- Right-click it and select Modify
- Enter 0 in the Value data section and then Enter
- The next thing to do is to restart your computer and that should take care of the error. If by any chance anything goes wrong because you have changed anything you cannot remember, use your backup file and fix it.
