Depends on what field you want to get into and/or what education you have or will get.  If you're going to get an associates degree in IT then probably you won't need the CompTIA+ but if you want to become a computer technician without much other experience then having a CompTIA+ can be a good option to show employers that you know how computer hardware works and you know the basics of being a computer technician.  I advise getting MTA, Network+ as well because they are quite relevant skills to being a computer technician.
 
My advice on learning them is to get books online, read through them and use them as study guides.  For CompTIA+ my advice is to go to computer stores and say you are trying to get it and ask if you could work there for free and get a feel for it.  Many will deny it but push it, and keep persisting.  For Network+ just get a network+ book and that's sufficient, if you have a router at home or a PC that can support virtualisation you can actually make a virtual network  for free using PFsense and Windows (PM if you want help with that).   And MTA Developer or IT infrastructure will help you understand software and the cloud and servers.  So a book is sufficient or even just watching Microsoft Virtual Academy which is free and offers heaps of great courses. 
 
I'm getting a high level associates degree in Network Engineering, and it's pretty lame and basic, so it's a good thing you're not doing it.  Because it's overpriced for what it is.  If you want to get a education, get a Bachalor Degree and if you want to go higher, get a masters.  My goal is to get a masters in Information System and Business. Good luck.

Are you using a fully-activated and updated version of Windows 7?  I can remember when I was on Windows 7 having similar issues but it was showing more disk space than it was actually using.  Either way I wouldn't be worried.  As @SageOfSpice stated, WinDirStat might be a good option to find the biggest files and/or folders on the system to see what's actually going on.

I'm not really sure what you mean, I personally wouldn't use CCleaner as it's a registry cleaner.  I believe CCleaner has been bashed by Microsoft before. I think it's fine for only file cleaning.  My advice is to restart your computer and then check.  If that doesn't work then I'm not sure what could be causing it, no doubt it is something In the registry, which is like the /etc folder in Linux.  So all the configs and stuff is in the registry, hope you didn't clean it, if you did try and run a system restore.
 
Good luck.

I wonder if you could at least get three separate external IP addresses from the ISP.  That way you could have hook a switch up to the modem and wire Ethernet to each floor.  Not only that but then you'd be supplying a drop to each floor and the tenants themselves can handle buying their own routers and manage their own routers and since everyone is behind a NAT, no one can pry into anyone elses internet.  ...I don't think.
 
Like, if this HAS to be one shared internet connection, separate IPs would solve a number of problems.

2 main reasons:
 All these trial software are there because they help drop the price of the system. The market have shown that consumers don't consider junk level in their price. They want the cheapest price for the specs. And we see this behavior time and time again. Heck, just say Alienware, and you have an army of people telling you how overpriced they are, even taught they are limited in junk compared to other brands. Sony, when they used to make PCs, used to have an option to get a system junk free, but you had to pay 50$, and sadly that was not popular. People basically said "I'll remove it myself, and save 50$ (if I recall correctly)" (although, one can argue that they probably spent 2h doing this, assuming they do it, and the time and energy spent is just not worth the 50$ saved). For Dell, if you order through the small business section, you have (sorry, my experience is from 2009, I don't know how it is today) junk free, with even the OS disk (no recovery image) included (and superior warranty service, where they listen to what you say on what you tried, and local during office hours). But of course, you pay a premium over this, but that bring little to no interest. People prefer the lower price.
  "Value-added software". For most consumers, benchmark and overall performance is not in their mind. All they want is a better system than what they have (which also have junk), so they get a nice, newer and therefore faster system. But what they care, and part of their decision making is having that "nice" looking utility to control the RGB LEDs, or this cool touch screen interface they saw at the store, etc. And consumers will pick a system over another one for this. We tech, we know it is all rubbish. As doing IT services, I cannot count the number of times where I help install their printer drivers, where I install JUST the driver, and they ask some  poorly coded utility that they REALLY want to do silly stuff with their printer, that most likely they'll use once in their lifetime, but they got sold by it. IE: This is why they got printer A over B.  
What are some options for PCs?
See if you order a pre-build system over the small business section of the manufacture website (you don't need to be an official business. They don't ask, and they don't say no to money), and see if you can call to order to do a request of having a pre-build system junk free. They might even do it for free.
  Get your laptop from Microsoft online/offline store. Look for "Signature Edition" systems. These are systems where you'll still have the manufacture utilities and stuff, but Microsoft make an arrangement with the manufacture to not have the junk. MS pays the difference. So the system price is the same, but without the junk. Now, you just have the OEM software to deal with, and now you can pick what you care or not about (for example, say you have RGB keyboard, remove everything but utility to control the RGB keyboard lights)
  Surface. Those are super clean... to clean in my opinion, where you don't even have the driver control panels. So any changes is through the registry. Sucks for the non tech guy. And of course, Surface line is definitely not affordable. How about printers?
Get office focused brands, like Brother. Junk free drivers.. well, you have the option in the installation what to install, and even the junk is fairly light.  Easy to service, no tricks with toners, even have an override mode where you can print regardless of the empty state of the ink, to get the last drop, ink is cheap, and you can refill easily (although they don't recommend it of course), solid build quality, not too expensive, small in form factor which makes it acceptable for home use. You have brands that don't enforce their junk with their drivers either.
  Anther way, is to use Windows drivers, this way you have just the drivers. Success rate is higher on more simpler printers, especially non USB ones. But many times you can find printer drivers built-in Windows that might not the exact same model, but the model is for the same CPU and protocol that the printer use, and you'll have just the drivers installed, and no junk, and it will fully function. (Might need the junk if you have a printer+scanner system to get that scanner utility)  

Because they can make a lot of money.  Mcafee for instance, when a user purchases the product from a bloatware installation the computer manufacturer gets a cut.   If you * that cut by 10,000.  That's quite the chunk of cash.   I can imagine a reason for companies to do it on very affordable computers, but not the high-end.  Seriously, that is a dick move to put it on a computer a company is already making a decent profit off. 

I did it this way; it is really hard to read but works

Basically I scaffolded where the original tables should go instead of trying to add around it the tr tags; as that was SUPER CONFUSING.
 
then copied and pasted the original tables in
 
I will do this from now on for things that are too complicated to read

Linux apparently uses GCC as it's compiler which is why they're affected. Most of us Windows users have installers that do things automagically (<- not a typo). Linux users may have to compile their installs on their own. 
 
I'm a Windows 8.1/10/Linux Mint user and haven't run into this issue since I'm on Haswell, but I can see why it'd be a huge issue. 

People get mad because they think you are depriving your parents of things by having a good computer, let alone a very over-powered computer.  .If you begged your parents for the computer then that's one thing and you're a dick.  But if your parents freely gave up things because they wanted you to have a good computer then it's their choice.  
 
While I understand why people would get angry, in the end you shouldn't care and just tell people to mind their own business.  I don't agree with letting your parents dish out a whole lotta money for your rig but it's not my business.

You should add an exception in Norton so it will stop flagging it.
 
Alternatively, and this is of my opinion, if you have an SSD, don't bother with a RAM Disk.

Nothing is wrong with having a good PC, or building your PC, or buying expensive things.  But there is a problem with acting like your better than everyone else because of it.  And claiming your smart because you can put some pieces together.   The whole "PC master race" thing is a pile of crap.  It's crap to make people without jobs and who spend all their time gaming on a computer they spent 2 years wages on better. 

Microsoft is turning Windows into a service, slowly but surely.  We are all frogs in a pot with water getting increasingly hotter.   As time progresses I guarantee unless Microsoft gets a change of heart we will see more and more ads, more tracking and at some point the inability to even log in with a local Windows account.  
 
Microsoft tried it before, and it didn't work.  They are still pushing the same thing just much more slower to fool everyone into thinking they've actually changed their ideology.  Google, Microsoft, Amazon, Facebook.  I don't give a damn, I just don't want to be tied into any of their services.  Like leeches that live off information and the entrapment of others. 

My personal recommendation is Java or C#, they are widely supported (especially Java) and Java can run on any platform.  Python is good too, but the real thing is that it doesn't necessarily matter that much which language you choose, as long as you can use it to achieve your goal.  
 
I personally suggest Java.  But you can go with c++ or anything else if you want to instead.  I would say Javascript but in my opinion it has a couple twerks and weird things and can be a bit annoying unless you know how object oriented programming works, and know your way around datatypes, functions, basic operators and program structure.  
 
As to learn programming, of course it takes time and practice.  And experimentation and imagination.  But I suggest using a book, while online video courses are great I really think the classical book is the best way to follow along and learn a new language.  The main books you want to pay attention to are the ones with challenges,  such as this book here: https://www.nostarch.com/thinklikeaprogrammer.   Just my opinion.
