Once Windows 10 has been properly activated, it’s not necessary to enter the product key again. After the installation, the device will activate automatically as soon as it connects to the internet.
Before you proceed with the clean installation process, you should confirm that your device is activated using these steps:
1. Open Settings.
2. Click on Update & Security.
3. Click on Activation.
Under the “Windows” section, confirm that your computer is activated.
After you complete the steps, if your current setup is activated, then Windows 10 should reactivate automatically after the installation.
