Can anybody help me resolve this Windows 8.1 Issue?

Question

In summary, a couple of hours ago whilst surfing the internet, a message popped up on my screen and without doing anything told me that my computer was "installing Windows 8.1", and no matter what I did it wouldn't let me exit, and not being all
that tech savvy when it stated "Do not turn off your computer", for me that meant "leave it alone".
So, I thought, "Ah, oh well. Another Microsoft update -- probably better than 8." Up until now, I have never been so wrong; I am not trying to criticize Microsoft or anything, but because of the issues that I have had so far(which aren't really
that huge, but have impacted me) have interrupted my experience and entertainment that I use my computer for.
Down to the issues. So, when my computer started up it took me to the screen where all the tiles are, and everything was huge(when I say huge I mean  one of the tiles took up 25% of the screen), so basically I had to go to PC Settings and change the
size from default to smaller in "PC Settings>PC And Devices>Display", which was problem solved. But, whilst searching for how to make it smaller I had to go on Google Chrome, which when I opened up went from
[UPDATE] Since I cannot put images or links in this "Body Text", because my account is not verified yet, basically I'll try to sum it up in words.
Before(Good In My Opinion)
It's just like when you first get a computer -- the toolbar is small so that 90% of your Google Chrome is accessible, and your toolbar below where all of your icons such as Internet Explorer, Windows Market, Documents, etc. are, are also small, but small
enough so that it is unnoticeable UNTIL you WANT to notice it.
to bad (what the...)
Notice how everything is a lot bigger, especially the tool bars and things at the top, and because of this I have to adjust to this odd output, and in addition have to scroll to see more of a page because even the page seems more zoomed in. (I've even tried
using "Magnifying Glass", but that only temporarily HALF solves the problem.
Another problem is that everything on my screen is just generally bigger. I've tried changing it numerous ways; I've tried NVIDIA Resolution, etc. I've tried PC Settings>Resolution, PC Settings>Devices, etc, but nothing seems to work -- even the resolution
change doesn't do anything. As you can see, at the bottom of my screen all of the stuff is HUGE, and takes up at least 1/30th of my screen, when before was small and easily unnoticeable until I wanted to use it.
If anybody could help me, or solve these problems it would be HUGELY appreciated as I cannot stand this any longer.
Thank you.

Hi,
The main problem is that everything on the screen is bigger, right?
Considering you have tried PC Settings>Resolution, PC Settings>Devices ,I recommend you check another setting “Change the size of all items”. Here is the path:
1.Control Panel\Appearance and Personalization\ Display(Change the size of all items)
2.If #1 won`t work, I agree with
ZigZag3143x,I recommend you re-install the graphics driver and it is essential to download the right driver for Win8.1 from the manufacture website.
