Windows 10 Editions by Brett Howse on May 13, 2015

This will be the main version sold on all consumer desktops, laptops, and larger tablet form factors. It will include continuum to transform from a desktop operating system to the touch friendly tablet version, and of course include things like Cortana. Although not specified, if it continues the tradition of Windows, Home will not be able to be joined to a domain and will be missing the business features.

I don't think they are trying hard to convert everyone to touch screen using Windows.  But, they are, of course, aware that touch-screen computing devices are becoming more common and they want to be a full player in that arena.

soybean is right.
Imagine a company that makes tennis shoes. But it learns that many people use them for running shoes. The company will cater to both groups.
Example: Think  of Nike or Reebok. Imagine what would happen if they announced that from now on they would only make shoes to be used on a tennis court. Common asphalt would destroy the shoe and void the warranty.
Absurd? Yes, that is my point. Imagine is either r Apple or Microsoft made and OS that would only work on a touch screen. It will never happen.
