    A few days ago, I installed a fresh copy of Vista Enterprise on my laptop, using a DVD ISO image from the MIT / Microsoft Campus Agreement website.  I did not have to enter a product key - it was encoded into the ISO image in some way.

    This evening, I booted up the laptop, and upon logging in, was presented with a screen that says "An unauthorized change was made to Windows", and "You must re-type your Windows Vista Enterprise product key to activate".  As I stated, I was not issued a product key.

    At the moment, I cannot use the computer at all.  The dialog has only two buttons - "Next", which complains about me not entering a product key if I click it, and "Cancel", which just dumps me back to the login screen.  If I reboot in safe mode, I just get a dialog saying I need to reboot in Normal mode to activate Windows.

    This is an absolute joke.  And people wonder why Apple is gaining market share.  Why should I put up with this?  I have work to do tonight, and this idiotic operating system has decided not to let me log in to my own computer because it's not happy with the licensing or something.

    Good Morning Avalys,

    Please run the Microsoft Genuine Advantage Diagnostic Test (MGADT) so that I may analyze the results.

    By clicking the link below, you will download the MGADT.  Then click the Run button. Then click the Run button again. Then click the Continue button to perform the diagnostic. The Windows tab should show, click the Copy button to paste your report to the clipboard.  Then paste the report into a New Post on this Forum by adding a post in it and pressing Ctrl V (to paste the text). Clicking the OK button will clear the Diagnostic window. Here is the download link:

    Please tell us about the Certificate of Authenticity (COA) for your copy of Windows Vista.

    1. What edition/version of Windows XP is titled?

    ·         Home Basic

    ·         Home Premium 

    ·         Business

    ·         Ultimate

    2. Does it read "OEM Software" or "OEM Product" in black lettering?

    3. Or, does it have the computer manufacturer's name in black lettering?

    4. Please provide the customer scenario you are experiencing.

    5. DO NOT post the Product Key. 

    Not sure what to look for, see this page to reference your COA:

    NOTE: The data collected with the MGADT does NOT contain any information that can personally identify you. The information can be fully reviewed, by you, before being posted.



    Thank you for your participation here on the Genuine Advantage forum. We look forward to working with you.
