With Microsoft ending support for Windows 8 long ago, you have to fully uninstall Windows 10 to rollback to a previous version.
Be aware, too, that new computers (especially tablets) may contain components that weren’t manufactured when older Windows versions like Windows 8.1 or Windows 7 were being sold.
Though the guide below is written with rolling back to Windows 8.1 in mind, the basic steps work for any Windows operating system going as far back as Windows XP - though we don’t recommend going that far back, as Microsoft ended support for it some time ago. Windows 10 has been a critical success since its release, but if you need or want to revert to an older version of Windows, you can uninstall Windows 10 and downgrade to Windows 8.1.
