An Unauthorized Change To Windows (validation lost) RRS feed

  • Question

  • Dear Sir or Madam,

    I have an "An Unauthorized Change To Windows" problem as well. I have done all my investigations and trials learned from this forum, including run "net start slsvc". However, it still does not work.

    I guess I have to "remove imcompatible softwares including recent windows update" according to the instructions following "validate windows" process. My stupid question is:

    (1) How can I remove recent windows update without having access to control panel?
    (2) How can I determine which windows update I have to delete, and how to avoid to install them in the future?

    Thank you very much for your reply in advance.

  • Hello Hzn,

    We request all users initially run the Genuine Diagnostics tool to try and identify the problem you may be experiencing.  Did you receive any error codes and/or statements whatsoever indicating a failed validation?  Please try validating windows again by visiting the following location:  http://www.microsoft.com/genuine next click on the "Validate Windows" button in the upper right corner.  What happens?  The genuine site can also provide you with valuable information so please take time and review the documents.  Another site for helping customers identify genuine vs. non-genuine software is located here:  http://www.microsoft.com/resources/howtotell/


    Next please download and run the utility at this link http://go.microsoft.com/fwlink/?linkid=52012, then click the Windows tab, Copy to Clipboard, then paste the report into a New Post on this Forum.  This would assist us immensely so we may analyze possible causes for a failed validation.  Next we will begin formulating a resolution for what may be causing the problem.


    Step 2 is telling us about the COA. Tell us:

    1. What edition of Windows XP is it for, Home, Pro, or Media Center?

    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. DO NOT post the Product Key.

    5. Please also provide a short description of the issue you are experiencing.


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

    Thank you,
