Run the MGA diagnostic test and see what it says
Valued Customers,
We understand the inconvenience you are currently experiencing and would
like to provide you with some self-help options we have made available
for our customers. Please follow the steps outlined below as it could
either resolve your issue or, if need be, provide us with additional
information to determine the cause of this issue.
1. Ensure you log onto the computer experiencing the issue with
“Administrator†rights.
2. Next we would like to confirm that you are running the most
current version of the Genuine Advantage control on your computer. In
order to do this please follow the below link and choose the “Validate
Windows†option.
http://www.microsoft.com/genuine
If the above steps did not resolve your issue lets continue with the
steps below.
If you could also please follow the steps outlined below, the
diagnostics Web Site will attempt to resolve the validation errors you
are experiencing with Windows.

Next follow the on-screen prompts to resolve the issue if any of the
checks at the above site fail. If, after attempting to resolve the issue
as per the instructions on the above site fails, please refer to the
link below and run the MGA Diagnostics tool:
http://go.microsoft.com/fwlink/?linkid=52012
You will be prompted to either “Run†or “Save†the tool. Choose to “Runâ€
the tool and follow the on-screen prompts. You will receive an “Internet
Explorer-Security Warning†dialog box for the “Windows Genuine Advantage
Diagnostic Toolâ€; you must choose to “Run†this tool when prompted.
Once you are presented with the Diagnostics tool choose “Continue†to
run the diagnostic report. If the “RESOLVE†button is available after
running the diagnostics, please click “RESOLVE†to allow the diagnostic
tool to attempt a repair.
1. After running the MGA Diagnostic tool, click on the “Windowsâ€
tab and then click on “Copyâ€.
2. Please return to this post and “Paste†the results here for
additional review.
Step 2 is to look on the computer itself, in the documentation you
received with the computer or with your retail purchase of Windows to
see if you have a Certificate of Authenticity (COA). If you have one,
tell us about the COA. Tell us:
1. What edition of Windows XP is it for, Home, Pro, or Media Center, or
another version of Windows?
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.
Not sure what to look for? See this page for reference:

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,
