I have a old Acer Aspire az5101 ALL IN ONE desktop, it still run windows 7 home premium, I was in Device and Printer just to check for my printer drivers and saw I need to fix a troubleshoot, so I found out it was my Microsoft Teredo Tunneling Adapter never
knew what this was but I follow this instructions from LemP and it WORKS . This is what I did
If the Microsoft Teredo Tunneling Adapter is showing in your Device Manager with a warning icon, open the
Registry Editor
(click Start )
type regedit
press Enter
and respond as needed to the UAC prompt) USER ACCOUNT CONTROL
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP6\PARAMETERS
Look in the right pane: if there is an item named
DisabledComponents and its value is not 0, right-click on the item, select
"Modify" and change the value to 0.
Then Restart the
Computer.
Thanks for the help LemP.
