Invalid vista home premium product key


  • My power cord got disconnected and for some reason upon starting I had an activation box come up saying " The Windows Vista Home Premium product key you typed is invalid for activation". I have had my computer for 4 or 5 years and have never had this come up. I have typed in the key thats at the bottom of my computer but its telling me its invalid. I am lost as to what to do. Can someone help me sort this mess out and how on earth it happened?

    Thanks in advance

  • Hi,


    You can try the Phone activation as below:


    1. Click the Start button, type "SLUI.EXE 4" (without the quotation marks) in the search box, and press “Enter”.


    Note: There is a space between "SLUI.EXE" and "4".


    2. Select  the neatest location, and click "Next".

    3. Please click "Continue" when the User Account Control dialog-box appears.

    4. The Windows Activation will generate a toll-free phone number, 1-866-740-1256 for US, 1-866-740-1256 for Canada. And the installation ID will be displayed, please follow the on-screen steps to activate it.
