Need help with Windows 10 activation? Ask your quick question!
You've connected your old hard drive to the new PC and noticed issues with your Microsoft account activation. The system reports error codes 0xc004c003 and 0x803fa067. It seems there may be a mismatch or compatibility problem between the old drive and the Windows 10 Pro license.
You possess a "Digital Licence." Begin by looking up "CMD" and executing it with administrator privileges. Input the command "SLMGR /ATO" to launch the Licence Management tool, selecting the option to activate your Windows. It seems your previous licence may no longer be valid since it was tied to an older mainboard model. If you have a "Windows 7 Pro/Ultimate" or "Windows 8, 8.1 Pro" licence, you might attempt activation using these. This should function and grant you a current digital licence. Using the above command, you can also try reaching out to the activation servers. To enter a licence, run CMD with "SLMGR /IPK "YOUR WINDOWS KEY HERE".
