Solve “This Copy of Windows Is Not Genuine” – Error 0x80070005

🔍 Common reasons this happens

This situation often occurs when:

• Activation components were damaged or removed during an update

• The system was restored or reinstalled and activation was never completed again

• A different Windows edition was installed over a previously activated one

• Microsoft’s activation servers temporarily can’t verify the status

✅ How to fix it

1. Restart your PC
   In some cases, a restart is enough for Windows to refresh its activation check.

2. Enter your product key again
   Go to: Settings > System > Activation
   Click Change product key
   Enter the key you received and click Next

This often forces Windows to re-check activation and removes the warning message.

3. Run the Activation Troubleshooter
   In the same Activation page, click Troubleshoot and follow the prompts. Windows will attempt to detect and correct activation-related issues automatically.
