No Mac has Windows off the shelf. It can be installed after Purchase, but there is no Mac that comes with Windows pre-installed. Windows belongs to a Microsoft, a competitor to Apple, and as such it's very unlikely a Mac computer will ever come with Windows pre-installed.
Beyond that, currently no Mac has, nor has ever had a touchscreen.
Whether one will come out or not, is impossible to say, as no one here is privy to Apple's development plans.
If you need a Windows computer, that has a touchscreen, Microsoft (not Apple) offers their line of Surface computers.
Other's like Dell also have offerings with touchscreens.
