All editions of Windows 8 can be in-place upgraded to Windows 10. However, only retail editions of Windows 8 that are first updated to Windows 8.1 will receive the Get Windows 10 app delivered via Windows Update. Alternatively, Windows 8 computers can be upgraded to Windows 10 using the Media Creation Tool or directly from USB/DVD Media.
Before upgrading to Windows 10, it is recommended that you install all the available important Windows Updates. This will ensure a smooth upgrade process.
