Windows Not Genuine

Hey guys,

Not sure if posting in correct forum but here we go.

Had Windows 7 Ultimate 64-bit for around 4 years, worked perfect. Last week I upgraded to Windows 10 Pro 64-bit and recieved the error message 'Error code: 0xC004C003' after being cut off 3 times from there SLUI 4 call system i'm looking for another route. The Windows Genuine Advanced Diagnostics Tool gives me error 'Failed to create output files, hr = 0x80070002. Please contact support.'

You can't use MGADiag on a Windows 10 system - it only supports Win 7 and below.

It's likely that your problem is caused because either

1) you installed after booing from the DVD

or

2) your windows 7 install wasn't genuine.

For proper analysis,

Please repost your Windows 10 query to the appropriate WIndows 10 Community forum here...

Thanks for the heads up Noel.  Moved

Did you clean install the upgrade?

This product key didn't work. (Error code: 0xC004C003)

License could not be found or was invalid. (Error code: 0xC004F034)
          What it means and how to fix it

          There are a few reasons why you might see this error:

  • You performed a clean installation of Windows 10 instead of first upgrading from your previous version of Windows. When this happens, we aren't able to register your entitlement with the activation servers because you aren't upgrading to Windows 10. To fix this, you'll need to go back to your previous version of Windows, make sure the previous version is activated, and then upgrade to Windows 10. For more info about how to go back to a previous version of Windows, see the section in Recovery options in Windows 10.

  • You upgraded to Windows 10, but the activation servers were busy. If you upgraded from an activated copy of Windows 7 or Windows 8.1, your copy of Windows 10 will be automatically activated, or you can wait a while and then select Activate now. If you performed a clean installation instead of first upgrading to Windows 10, see the info on how to fix this problem in the previous item.

  • You might also see this error if you're using an invalid product key. For example, you can't use a Windows 7 or  Windows 8.1 product key to activate Windows 10.
