  • Hi Robin

     

    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.

    Or

    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

     

     

      Your issue may be related to the errors you saw during Windows Update. I suggest that you look at was updates (would be in the form of KBxxxxx) were installing when the install errors occured and instead of letting Windows Update install them, install them manually by going to http://download.microsoft.com and searching for the KB number)

     

      If none 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.

  • Could not complete step1:

     

    - Downloaded Vista 32 SP1

    - Set up to 'clean boot' (as per 629135)

    - Re-Started windows in safe mode.

    - Set screen saver to 120 mins

    - Ran installation of SP1

     

    Started for 15 minutes then gave following error message:

    Retried with same result

     

    Internal error Occurred while installing the Service Pack

    Error Code: 0x800B0100

    go to http://go.microsoft.com/fwlink/?linkid=101139

     

    Tried this but can not complete step 1 of resolution 1 as do not have access to 'Start' in Genuine MS detection mode NOR will Windows Update start in Safe Mode.

     

    Have also attempted to restore from previous backup - but now no restore points are being displayed.  They were there earlier today.???

     

    The last fall back point is I have an HP Backup & Recovery Disk available that I created in APR-08

     

    Next steps please!
