Unauthorized changes made to windows error (Vista x64) RRS feed

  • Question

  • HI. I got that "Unauthorized change made to windows" message this morning (this seems to be a rather pervasive issue, if the posts I've seen here are any proof). I had last used the my PC on the 5th of July (It's been packed up since then), and it was working fine, with no evidence of any validation issues. I turned it on this morning, and encountered the aforementioned "bundle of joy". I realized relatively quickely it might be a registry issue, and restored it to a previous state. That didn't work, so I thought it might be something I installed. I most recently installed Unreal Tournament 3 (with the associated Dedicated Physics Software, can't remember the name)  Anyway, I uninstalled that (and later found similar advice regarding software that could take 3 or so days to trigger Windows Tampering Protocols) and restarted my PC. Unfortunately, it didn't work (though using the advice just mentioned, I did see UT3 was the last program installed that showed any issues on the other diagnostic tool). I figured it might be a more serious issue, and so performed a system restore. It also failed. I'm at a loss. Given the info below, can you possibly surmise what the issue is? I have the VIsta Ultimate box available, but I'd rather not have to re-install and lose a good chunk of my data. Any help you can give would be appreciated. Thanks!

  • Hello

    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 matches 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.
