An Unauthorized change was made RRS feed

  • Question

  • Hiya,

    I very recently received an 'Unauthorized change' message with the error code: 0xC004D401. Fairly certain I hadn't installed any new software around the time the error popped, also checked the list of incompatible software and I'm clean there.

    Got the info from the MGADiag.exe here:

    Hello Lloiger,

     

      The core to your particular issue centers on the line in your Diagnostic Report that reads:

     

    File Scan Data-->

    File Mismatch: C:\Windows\system32\uxtheme.dll[6.0.6000.16386]

     

    This line means that the critical system file uxtheme.dll either:

     

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

    Or

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

     

      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.

     

      Normally I would resolve this type of issue by having you install a past update that contained that file. This would replace the bad file with the known-good copy. But there are No Updates that contain file uxtheme.dll. So the only other ways, that I know of, to possibly resolve this issue are:

     

     

    A) Repair Windows using System Restore:

     

    1) Reboot Vista into Safe Mode

    2) Go to Control Panel

    3) On the left hand side of the Control Panel window, Click on "Classic View"

    4) Double-click "Backup and Restore Center"

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

    6) 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 Before you first noticed the issue.

    7) Click the "Next" button.

    8) Reboot back into Normal mode

    9) Vista should no longer be in Reduced Functionality mode

     

    B) Repair Windows by booting from the Vista DVD and selecting the "Repair" function.

     

    C) Reinstall Vista


     

    Thank you,
