Windows 7: Windows not genuine after SP1, but Disk is OEM ! HELP!!

Windows not genuine after SP1, but Disk is OEM ! HELP!!

I work in a custom-build/repair shop. I've run into this twice now, and can't explain it:
We're a Microsquish Partner, and install the OS that we order with a new machine.
I was installing service pack 1 from my portable hard drive to PC's to prevent downloading it from Windows update every time.

Now I've run into custom built OEM PC's returning to the shop because they are getting the "Windows is not genuine" message AFTER it was installed from the OEM disk, and activated.

Someone stated to me that the service pack I was installing, was an "older" version. Not sure, but I have another PC coming in today or tomorrow with the same issue. BTW: I can guarantee the Windows disks we install are not pirated.

Thanks in advance...

Hello Jeff, and welcome to Seven Forums.

If you have not already, you might see if after changing the producting key number to the number on the OEM product license key sticker may allow it to activate with that number instead of with the OEM SLP key.

Hope this helps,

There's a good probability that the original install is from a counterfeit disk
Installing SP1 breaks most hacker's Loaders, with the result that the updated system fails WGA.

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 - )
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.
- **in your own thread**, please
