Got error code 0xC004D401 RRS feed

  • Question

  • I have bought note book for 1 yr and today when I open it, I got a message "An unauthorized change was made to Windows" and error code is 0xC004D401 (my window is vista home edition)

    I have gone to " Windows Vista Genuine Validation Results" pages, and got the message " This copy of Windows did not pass genuine validation." But I am sure that I have not installed such a program that described in that page.

    And when the message box
    "An unauthorized change was made to Windows" is popped up, I can not open the window of control panel and my computer's property.

    I'm not sure this is the same problem or not but when I start my computer I will got a message that file "TMP623.tmp" can not be open. However I tried to find this file but I couldn't find it anywhere.

    Then I would like to know what can I do next? Please solve my problem as soon as possible.
    Thank you in advance.

  • Chin,

    Unfortunately virus's falls outside the scope of the WGA support forum. Do you have all of your data previously backed up? If not I would try your best and back up any of your data. A great way for backing up information is having an external USB hard drive. If you don't have this use CD or DVD Rom media and back up all you can. Keep in mind Chin you should run virus scans of this data prior using again. The best way for defeating viruss is to perform a complete system re installation.

  • Hello Chin,


    Thank you for providing the error code. I know what may be causing this but first can you please run the MGA Diagnostic Tool and provide the results back in this thread?  

    Please run the Microsoft Genuine Advantage Diagnostic Test (MGADT) so that I may analyze the results.

    By clicking the link below, you will download the MGADT.  Then click the Run button. Then click the Run button again. Then click the Continue button to perform the diagnostic. The Windows tab should show, click the Copy button to paste your report to the clipboard.  Then paste the report into a New Post on this Forum by adding a post in it and pressing Ctrl V (to paste the text). Clicking the OK button will clear the Diagnostic window. Here is the download link:

     http://go.microsoft.com/fwlink/?linkid=52012

    Please tell us about the Certificate of Authenticity (COA) for your copy of Windows Vista.

    1. What edition/version of Windows XP is titled?

    ·         Home Basic

    ·         Home Premium 

    ·         Business

    ·         Ultimate

    2. Does it read "OEM Software" or "OEM Product" in black lettering?

    3. Or, does it have the computer manufacturer's name in black lettering?

    4. Please provide the customer scenario you are experiencing.

    5. DO NOT post the Product Key. 

    Not sure what to look for, see this page to reference your COA:

    http://www.microsoft.com/resources/howtotell/product.aspx?pID=b5c507e5-3522-40de-a2f4-97d82b39cc47&cID=ea710cad-37b0-4975-bcd6-abfee19961df&method=oem&displaylang=en

    NOTE: The data collected with the MGADT does NOT contain any information that can personally identify you. The information can be fully reviewed, by you, before being posted.



    Thank you for your participation here on the Genuine Advantage forum. We look forward to working with you.

  • Good Morning Chin,


    The error code you are receiving requires re-activating Windows but could have other concerns associated as well. First lets try and activate Vista and see if this will rectify what you are experiencing.  Please review the following Knowledge Base (KB) article and refer to the resolution portion of the webpage:

     

    KB931573 – You may be prompted to activate Windows Vista on a computer on which Windows Vista was already activated by a Volume License or OEM installation

     

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;931573 

     

    If the above does not resolve your issue, please follow the steps below. If the first set of steps does not resolve, move on to the next set of steps.

     

    ----------------------------------------------------------------------------------------

    Step set #1

     

    1) Open Internet Explorer

    2) A Browser will open, type: %windir%\system32 into the address field

    3) Find the file cmd.exe

    4) Right Click on the cmd.exe and select Run as Administrator

    5) Type: cscript slmgr.vbs -rilc (It may take a long time for this to complete, please be patient)

    6) Hit the Enter key

    7) Reboot 2 times

     

    -------------------------------------------------------------------------------------

    Step set #2

     

    1) Open Internet Browser

    2) Type %windir%\system32 into the browser address bar.

    3) Find the file CMD.exe

    4) Right-Click on CMD.exe and select Run as Administrator

    5) Type: net stop slsvc  (it may ask you if you are sure, select yes)

    6) Type: cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareLicensing

    7) Type: rename tokens.dat tokens.bar

    8) Type: cd %windir%\system32

    9) Type net start slsvc

    10) Reboot Twice

    11) Windows Vista may require you to enter a Product Key [use the Certificate of Authenticity (COA)] SLP Product Key found on the sticker on the side or bottom of your computer and activate. Use the Activate by Phone method outlined below.

    From the Desktop:

    a) If you have access to the Start button: Click the Start button, and type in "slui.exe 4" in the search field and then press the "Enter" key. This will bring up the Activate by Phone dialog window. Follow the steps provided by the window. The phone activation process should only take about 6 minutes.


    b) If you do not have access to the Start button: Reboot and login to Vista, a dialog window will come up. In that window, click the option "Access computer with reduced functionality". Once you do that, Internet Explorer or Firefox browser will open. In the address bar type "c:\windows\system32\cmd.exe" press enter, a new window will come up, type: slui 4 and hit enter and follow steps to Activate over the Phone.

    Also you may reference the following site for various Telephone Activation Centers:

  • Good morning Stephen,

    It looks like this link doesn't work for me too (http://support.microsoft.com/default.aspx?scid=kb;EN-US;931573).
    (like the one that download MGADT)
    So I tried to use next step but after I typed "cscript slmgr.vbs -rilc", it only took a second to reply me that
    "slmgr.vbs(291,5) (null):0xC004D401".
    This is not like you said then I stop to continue next step.
    Could you give me any advise?

  • Hi,
     I seem to be having the same problem. I tried opening the diagnostic page you proposed, but found nothing. Then i tried the step with the cmd.exe, but the only files i saw were:
    cmd.exe.mui
    cmdkey.exe.mui. and some others. When i right clicked these, there was no " run as administrator" option.
    But then, another files:cmd and cmdkey had that option when i right-clicked. Which of them should i choose.
    NB: The cmd had a C: in a black background. Would appreciate it if you could help. Thanks.
