After using it for years I now get message on screen "Windows Vista Build 6002 This copy of Windows is not genuine "

Thanks I managed to get that MGA Diag Report and copied it to the requisite site and now await a response to the report

Your report is only a very partial one - I suspect produce by means other then those I recommended....

Please use the 'proper' method to get the results, and post them unedited, so that we can see the full status of your installatin......

To properly analyse and solve problems with Activation and Validation, we need to see a full copy of the report produced by the MGADiag tool (download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )

Once saved, run the tool.

Click on the Continue button, which will produce the report.

To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.

hi all i have exactly the same problem black screen windows not genuine etc from yesterday 28 5 11 have recently downloaded a free avg anti virus ?will try to fix tomorrow now as its late will let u know how i get on

After using it for 4 years yesterday I started to get message on screen "Windows Vista Build 6002 This copy of Windows is not genuine "

At the same time my desktop screen background is blacked out. My computer is an Acer Aspire L3600 on which Windows Vista was installed by the manufacturer.The computer was bought in January 2008 and since then has been operating satisfactorily until yesterday. I can still use the computer and although it has the black screen the icons are still there. However this and the reminders about validating my Product Key are irritating to say the least. When I sign in with my product key I am told it is invalid for activation. I have tried restoring to no avail. As the computer has been operating OK for 4 years, as it gets windows updates regularly, as the product key is still clearly marked on it, as it was purchased with windows Vista installed by a reputable manufacturer,Acer, as the computer was purchased from a major UK distributor, PC World, I find it inconceivable that my Windows Vista is not genuine and do not see why I have to buy a product key which is what I am being told to do to solve this problem. Every time I look on the Microsoft site for the price of the product key I am exhorted to buy Windows 7 and having gone round in circles cannot find a product key for sale. Is this problem planted by Microsoft to force us to upgrade to Windows 7?.

I have run the Windows Diagnostic Tool but cannot copy it except manually.

Your guidance would be appreciated and advice as to whether Window Vista will self-destruct if I take no action to resolve this problem.

Finally, I have Norton Internet Security 2011 installed.

It's not that easy, unfortunately - quite often this is the result of malware, but it can also be the result of badly-written software, or your Anti-Virus.

I've responded to your other post with instructions - if they fail, then please let me know what you're using as security software, as it may be a possible cause. Also whether it's up-to-date, and when you last ran a full scan.
