I have Windows 7 Home Premium but I wanted to install Windows 10 Pro onto a separate drive. I have a few questions about this.
  1. Will I need to buy a new license for Windows 10 Pro or can I install it for free even though I have Home Premium?
  2. Is there a way to tell Windows 10 (after I install it) that my programs are installed on a different drive, or will I have to re-install all of them?
