The Tor browser

[dyresand]

I say this because of windows operating system is not the most secure operating system in the world.

Yes, but that's because older Windows programs often rely on Windows not having some security features, and attempting to make Windows more secure will break the compatibility. There is no evidence Microsoft is spying on its users. If you ask me, I find it much more likely that Apple and Google are spying on its users. Apple iCloud is demonstrably very unsafe (Apple can easily read our data there), and Google is hiding exactly the code of the part of Chrome we'd need to study to verify Chrome is not sending our private information to Google during the updates.

Now, this is important get yourself a VPN you need that extra added layer of security and keep your ISP even safer than just using Tor.

What's your logic here? If you use VPN, your ISP can almost always tell that. If you are using Tor, you can make it hard for your ISP to see that.

you know HTTPS is a good thing right?

Yes, and that's precisely the point. Now, maybe the SNI does more harm than good (hackers manage to publish false security certificates in spite of it, and it enables many forms of tracking and censorship on-line), maybe HTTPS sometimes lulls people into false sense of security, but overall HTTPS is good. So, why not make it even better by using the Tor browser?

If you use a good VPN service that has no logs then no they cannot tell what you are doing. They can only see the traffic but they can't tell what you are doing. 
Linux is better because it is more secure of an operating system than windows. I would even say windows 10 with SLAX and Linux terminal is better than stock windows 10. 
You can do more in terms of security with the Bash terminal than with PowerShell. If you also want to be even more secure look at a good secure DNS server to connect too.
1.1.1.1 is a good example of a secure DNS server rather than using the ISP DNS they would assign to you.
