An unauthorized change was made to windows RRS feed

  • Question

  • I purchased a Dell Vostro 1400 laptop about a year ago but as I live in Guatemala didn't have internet until last week.  The machine worked fine until yesterday when a message appears saying that an unauthorized change was made to windows.  Two options are available: close the session or go online to check the reason.  The rest of the screen is black and I don't have access to the start button or my desktop or anything else.  When I went online a diagnostic informed me that my version of Windows Vista isn't valid.  I purchased the computer brand new from Dell and the license tag is on the bottom of the laptop but I can't seem to find out how to validate the version I have.  There were other suggestions to remedy the problem but I can't enter command prompt to initiate them.  Any suggestions?  Below I have pasted the diagnostic results.  Thank-you.

  • Good Afternoon Rufftuffy,


    The core to your particular issue centers on the line in your Microsoft Genuine Advantage Diagnostic Tool (MGADT) report which reads:

     

    File Scan Data-->

    File Mismatch: C:\Windows\system32\dnsapi.dll[6.0.6000.16615]

     

    This line means that the critical system file dnsapi.dll either

    a)      Has been tampered/modified/become corrupt to the point that its Signature Hash no longer matches the Signature Hash listed in Windows Vista's System Catalog.

    Or

    b)      The dnsapi.dll file has recently been updated but the file's Signature Hash was not updated, in Windows Vista's System Catalog to reflect the updated dnsapi.dll file's new Signature Hash.

     

    Windows Vista compares a Critical System file's Signature Hash with the Signature Hash listed in its System Catalog to determine if that Critical System file has been tampered with.

    In the case of the Critical System file dnsapi.dll, on April 8th 2008, Windows Update released Update Knowledge Base (KB) article KB945553.

    KB945553 – MS08-020: Vulnerability in DNS client could allow spoofing

    http://support.microsoft.com/kb/945553

    One of the things that this update did was to update Critical System file dnsapi.dll. We believe that, in some rare cases, after the Update updated dnsapi.dll, it failed to update Windows Vista's System Catalog with the file's new Signature Hash. When this happens Windows Vista compares the two Signature Hashes and when they don't match, Windows Vista's anti-piracy system thinks the critical system file has been tampered with and flags Windows Vista as Non-Genuine.

    To resolve your issue, we need to get the file's Signature Hash to match what is listed in Windows Vista System Catalog. I can provide a couple of suggestions to do this:

     

    A)     Uninstall Update KB945553

    1.       Reboot Windows Vista into Safe Mode

    2.       Go to Control Panel

    3.       On the left hand side of the Controlee panel window, Click Classic View

    4.       Double-click Programs and Features

    5.       On the left hand side, under "Tasks" click View installed updates

    6.       Sort the updates by "Installed On" date

    7.       Find the Updates installed on (or after) April 8th

    8.       Find the Updated titled "Security Update for Windows Vista (KB945553)"

    9.       Right-Click on the Update and select Uninstall

    10.   Reboot into normal mode

    11.   Windows Vista should no longer be in Reduced Functionality Mode (RFM)

    12.   You can manually reinstall Update KB945553 by going to http://www.microsoft.com/downloads/details.aspx?FamilyID=8203d303-c855-4579-9bbf-b06ddf5c1b87&DisplayLang=en  click the Download button, then click open (if any other windows pop-up, click the Allow or Continue button.

    13.   When the update is complete, reboot the computer. When the computer reboots, you should see a screen that says something like "Configuring Update..." Do not turn off or reboot your computer until Windows Vista has completed configuring the update.

     

    B)      Repair Windows using System Restore:

    1.       Reboot Windows Vista into Safe Mode

    2.       Go to Control Panel

    3.       On the left hand side of the Controlee panel window, Click Classic View

    4.       Double-click Backup and Restore Center

    5.       On the left hand side of the window, click Repair Windows using system restore

                                                                   i.      If the last thing that you installed was Update KB945553, then select Recommended Restore

                                                                 ii.      If you have since installed other software, drivers or updates, then select "Choose Different Restore Point", Put a check in the box that says "Show restore points older than 5 days", select the restore point that corresponds to the date you installed Update KB945553 (would be around April 8th or after).

    6.       Click Next button.

    7.       Reboot back into Normal mode

    8.       Windows Vista should no longer be in Reduced Functionality Mode (RFM)

    9.       You can manually reinstall Update KB945553 by going to http://www.microsoft.com/downloads/details.aspx?FamilyID=8203d303-c855-4579-9bbf-b06ddf5c1b87&DisplayLang=en  click Download button, then click open (if any other windows pop-up, click Allow or Continue button.

    10.   When the update is complete, reboot the computer. When the computer reboots, you should see a screen that says something like "Configuring Update..." Do not turn off or reboot your computer until Windows Vista has completed configuring the update.

     

    If, after you reinstall the update you re-experience the issue again, please go to the Windows Update Solution Center located below:

    http://support.microsoft.com/ph/6527#tab0

    Or create a (no cost) Windows Update support request located below: http://support.microsoft.com/oas/default.aspx?gprid=6527
