Windows 10: Another 0xC004c003 but think I know why but not how to fix The

I am getting the activation error 0xC004c003 invalid key like a lot of you too.

I upgraded a few windows 10 and they activated no problem but not this one.

I believe the problem is when I had windows 7 installed and activated I had to replace a hardware component.

When I had to reinstall Windows 7 to do this hardware change, Windows would not activate with my original key (OEM Version) so I had to go through the Microsoft phone activation and they give you new numbers to get it activated. It's not a new product key but the new numbers to get it activated. The phone verification thingie.

I believe microsoft is looking at my old product key and it is showing it is invalid as windows 7 did originally after the hardware change.

I looked up my product code when I reverted back to Windows 7 trying to fix this Windows 10 activation problem and it is still showing my original code even after the hardware change and re-activation with the new activation numbers.

If my Windows 7 was activated even after a hardware change I should still be eligible for the free Windows 10 upgrade!


Anyone know if this is my problem how can I get it fixed and Windows 10 activated?

Hi Pete,



Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.

Another 80070003 code error but i think i know the root cause

Another person here with the Windows Update fail getting Code 8007003. I think I know the root cause but I don't know the fix.

I've recently installed a faster and larger SSD to my desk top running Widows 7 (64bit) by cloning my old one over. I then had to make a small fix for the system to recognise the larger SSD in disk manager.

I've then tried to upgrade to Windows 10 but get the fail Code 8007003.

I've tried all the troubleshooting suggestions but can't get updater to update. Any ideas?

I'm thinking could do a work around and swap back to my old SSD - do the upgrade then clone it all again to the new SSD - I've not added much on the new SSD anyway and could save any new files to the back up drive.

I'd rather not do this so any easy fixes out there?

Thanks in advance

 

Same with me, replaced my HDD with SSD and called up microsoft on phone and the agent used a new code to activate windows 7.
i still have the code and also the key to my windows 7.
