If you’re running Windows 10 Home on your computer and you’re planning to upgrade to Windows 10 Pro, you know that you need to purchase a product key. However, if you’re not sure if the upgrade is worth it, and you want to give it a try, Microsoft offers a default product key that let you upgrade your system for free.
Of course, there is a catch, if you use the default product key to upgrade, Windows 10 won’t activate, as you need to actually pay Microsoft to get a valid product key.
In this guide, you’ll learn the steps to upgrade Windows 10 Home to Windows 10 Pro using the default product key.
How to upgrade to Windows 10 Pro
Click on Update & security.
Click on Activation.
Click the Change Product key button.
Enter the 25-digit product key:
As you enter the product key will trigger the upgrade process, then simply follow the on-screen instructions to complete the upgrade.
Once you complete the upgrade process, you can purchase a valid product key on Amazon, Microsoft Store, or click Go to Store on the Settings app to a product key from the Windows Store.
If you have a Windows 8.x Pro product key, it will also work to activate Windows 10 Pro.
Although you can always get a Windows 10 Pro product key and then upgrade, sometimes, you want to see if your computer will support the upgrade or you want to test the operating system before making the purchase, and using the default product key, you have at least another option.
