Get a new Windows product key

If your Windows product key is not valid, if you don't have a Windows product key, or if you lost the product key that came with your copy of Windows, you'll need to buy a new one to activate Windows. You must activate Windows online or by phone within 30 days after installation to use every feature of Windows.

To get a product key, go to the Microsoft website.
