I recently had to replace my mainboard and everything worked just fine for about a week. Then I suddenly got a message saying my windows 7 build was not genuine and needed to be activated. When I walk through the activation process, I get an
error message 0xC004E003. I cannot activate by phone (doesn't give me the option, only an error) and have tried the slui.exe 3 and 4, but neither works.
My Windows 7 OS was preinstalled by the manufacturer. Any help would be much appreciated!
UPDATE: I managed to resolve this issue. Apparently, the product ID was an OEM ID tied to the mainboard. Changing the mainboard led to a product mismatch. I found the original product ID in the battery compartment under the battery.
It didn't match the ID which I'd extracted from the registry when I was comparing them. I inputted the new ID and validation was successful. I hope this helps someone else.
