An unauthorized change was made to Windows. RRS feed

  • Question


    I fired up my trusty Dell laptop and had a message that An unauthorized change was made to Windows. I cannot get to my start menu and my laptop is now useless.  I downloaded the diagnostic tool and got this information:

    I have the sticker on this computer from the manufacturer and it has been registered and working fine for over one year.  Please, tell me what I need to do to fix this and how to prevent this from happening in the future.

  • Hello rakbit,


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


    File Scan Data-->

    File Mismatch: C:\Windows\system32\slc.dll[6.0.6000.16509]


    This line means that the critical system file slc.dll has either

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


    b)     Been updated but the file's Signature Hash was not updated, in Vista's System Catalog to reflect the updated 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. When this happens, depending on the file that has been tampered, Vista may show as Genuine or Non-Genuine, but either way, Vista won't Validate correctly and may also exhibit other strange behavior. 


      To resolve your issue, we need to replace or repair the file so it's Signature Hash matchs what is listed in Vista System Catalog. I can provide a couple of suggestions to do this:


    A)    Install Service Pack 1 for Vista (found at http://www.microsoft.com/downloads/details.aspx?FamilyID=b0c7136d-5ebb-413b-89c9-cb3d06d12674&DisplayLang=en). File slc.dll may be included in the SP1 install and if so, SP1 will overwrite the bad file with a known-good copy.


    (Note: this is the simpler way to resolve, but be aware that I have not received confirmation that slc.dll.dll is, in fact, included in SP1. So if this option does not resolve the issue, please see option B).


    B)    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


     If neither of these solutions resolves your issue, the last resort, that I can provide, is to reinstall Vista. But before you do that, create a (no cost)  support request at http://go.microsoft.com/fwlink/?linkid=52029 and see if they can provide any alternatives.


    Thank you,
