Do you need a product key to reinstall your Windows OS?
The product key is not required during the re-installation time, you can skip the license key step. But after the installation, you need a genuine license key to activate windows and use it properly.
However, there are a few exceptions. Microsoft allows anyone to download Windows 10 for free and install it without a product key.
