HP ProBook 6570b touchscreen and zoom?

[oureyespretend]

I just bought a HP ProBook 6570b laptop 2nd hand from a local college who was moving to a new campus and upgrading to new computers/laptops. Anyway, I bought this computer and it was reset to factory settings. It had Windows 7 and when I first turned it on it had a free upgrade to Windows 10 which I did upgrade to...though now I've seen a couple places people saying Windows 10 is not good? The main point I guess is that I don't know a lot about the functions and capabilities of the computer and what all it comes with. I have several questions but I have 3 questions to start with.

1. I tried putting icons on the desktop but have noticed that the touchpad allows you to zoom in and out much like on your phone. When I do this (usually by accident) all of the icons become huge and then when I zoom back out, they are all in different places. Is there a way to turn off this zoom function? While it may be handy for certain things, overall I've found it to be very hindering to basic use of the laptop. 

2. I've noticed that the screen orientation will often turn. These both seem to be functions that are compatible for a phone or tablet. However, again it becomes annoying when I'm just trying to use it as a laptop. Is there a way to disable this function ? I know it has a "Tablet Mode" which I would possibly be interested in using sometimes, which brings me to my next question...

3. Does this computer come with touchscreen capabilities? It has seems to have all the other capabilities of a tablet and even has the "Tablet Mode" but I have not been able to figure out whether it has a touchscreen or not, and if so, how to enable it. If not, how do I disable the other functions that are inhibiting basic functions of the laptop. 

Thanks for help with these issues and I welcome any other info on functions/capabilities of the laptop you think I might find interesting/useful/cool!
