To upgrade from Windows 10 Home to Windows 10 Pro, you will need a valid product key or a digital license for Windows 10 Pro. If you don’t have either of these, you will need to purchase one.
Tip: Before upgrading, make sure that your device is currently up to date with the latest version of Windows 10 Home
Once you have your digital license or product key ready for Windows 10 Pro you are ready to upgrade, use the following methods to begin:
Digital License
If you have a digital license you will:
- Select the Start button, then select Settings > Update & Security > Activation
