    Thank you for contacting the Genuine Advantage forum. Try this first.

    If you have a Microsoft Certificate of Authenticity (COA) for Windows Vista affixed to your system, then there is a strong likelihood your system is licensed to run Windows Vista.

    Windows Product Key Update Tool & Detailed Instructions:


    The Product Key Update Tool was designed to update a non-genuine Product Key previously used to activate Windows Vista with a known good Product Key.

    If you have antimalware or firewall programs installed, please make sure these programs are set to allow the Product Key Update Tool to have full access to the Internet.

    If this fails, then call Telephone Activation:

    From the Desktop:

    a) If you have access to the Start button: Click the Start button, and type in "slui.exe 4" in the search field and then press the "Enter" key. This will bring up the Activate by Phone dialog window. Follow the steps provided by the window. The phone activation process should only take about 6 minutes.

    b) If you do not have access to the Start button: Reboot and login to Vista, a dialog window will come up. In that window, click the option "Access computer with reduced functionality". Once you do that, Internet Explorer or Firefox browser will open. In the address bar type "c:\windows\system32\cmd.exe" press enter, a new window will come up, type: slui 4 and hit enter and follow steps to Activate over the Phone.

    Also you may reference the following site for various Telephone Activation Centers:
