Voice recognition works best with high-fidelity microphone arrays. In addition, some of the new features in Windows 10 Professional also require hardware to work.
In short, before upgrading Windows 10, the user needs to do a lot of preparation: book Windows 10 upgrade, back up important files, and pay attention to the anti-virus software life.
