  Yes, significant hardware changes, like replacing the motherboard or upgrading the CPU, can trigger the 0xC004C008 error. Windows may see these changes as a different device, thus requiring reactivation.

• Can I use a retail product key on multiple devices?

  No, retail product keys are generally meant for a single device only. Using the same key on multiple systems will likely result in the 0xC004C008 error, so it’s crucial to understand your licensing agreements.

• What should I do if I can’t fix the error myself?

  If you’ve tried troubleshooting and still face the error, reaching out to Microsoft Support is your best bet. They can provide personalized help to get your Windows reactivated.

• How can I prevent activation issues in the future?

  To avoid future activation issues, keep a secure record of your product keys and familiarize yourself with Microsoft’s licensing agreements. This knowledge will help you navigate hardware upgrades without running into activation problems.
