Have you considered switching to linux, linux mint MATE or cinnamon would probably be the most windows like, but ubuntu is fairly windows like too.
You can make live media to try out linux using tools such as unetbootin https://unetbootin.github.io/
if you download it along with the iso file for a linux distro of your choice (here are those for mint https://linuxmint.com/download.php
pick the 64 bit one unless your machine is only able to run 32 bit operating systems, most recent machines are 64 bit. MATE is a little faster as it is less pretty in terms of interface, cinnamon is considered more beautiful by some, xfce and kde versions are semi-experimental). You then need a spare USB to make the live media on, be aware that anything previously on this USB is going to be totally erased when you put linux on it, you only need a small cheap 8GB stick. You will then need to go into your BIOS/UEFI and turn off secure boot, along with disabling fast booting if it is offered and changing the boot order to put the USB ports as the first choice of where to boot from. With this done you can restart the PC again and give linux a try, do not install it immediately or you risk wiping your computer, just try it out and don't fiddle with any of the drive partitioning or formatting tools. Running live from a USb like this linux will be rather SLOW, this is because you are trying to run an operating system through the data bottlneck which is a USB port compared to the very fast data rates for a normal internal hard-drive.
But see if you like it, if so then when you shut down again (be warned anything you do in live mode will not be saved, so don't do any important work like this) and boot windows again you can prepare a few more things and get ready to install linux. I can provide you with more detailed tutorials on making and booting a live USB, it can be a bit daunting at first especially if you've never installed an operating system or changed BIOS/UEFI settings before.
I strongly suggest you don't go further than trying out a live USB, that is to say don't try installing linux to your internal hard-drive, until you've had a while to work out what things you do with windows and how/whether you can dod the same in linux after investigating linux equivalents to windows programs you use and after working out whether thngs like the wine compatibility layer are enough to let you replicate what you do on windows on linux. You don't want to try installing linux until you know whether you need to dual boot or whether you can wipe over windows, and f so what stuff needs backing up first.
If you don't want to try linux you could also try downloading install media for indows 8.1 or 7, under some circumstances it is possible to downgrade windows 10 back to an earlier OS. This way you can take control of updates again, but unlike switching to linux going back to windows 7 or 8.1 will only give you a few more years before your OS stops getting security updates.
P.S. when you boot linux, first thing to do is open the terminal and type in "sudo ufw enable", this must be done to turn on the firewall, which is the main security feature in linux.
P.P.S I too have some mild vision issues, 125% ("medium") is far more comfortable on wndows 8.1 for me to look at than the default 100% size is, and on linux too I find I need to set up fonts and such to be larger (changing it is siple in linux and once done it stays how you like it, unless you are running a live system which you won't be after you've tried it out a few times and either instaleld linux to an external drive (a good option, I do this), set up a dual boot (tricky) or wiped windows and replaced it with linux (probably too daring for now)). I guess all operating system designers probably work on huge screens and never realise what it is like to squint at default sized text on laptop sized screens.

Back on this site, for a while anyway, been so busy the last year.
My systems:2 laptops, intel i3 processors, windows 8.1 installed on the hard-drive and linux mint 17.3 MATE installed to USB
