I know exactly what you are talking about. I used Windows for at least 25 years, so you get used to how it is, and thats what you expect. You clearly want Linux to be the same, when it comes to ease of use, out of the box.
Linux has never really been that way though. Infact, over 10-years ago, Linux wasn't even friendly at all for the home user! But thankfully, Linux has gotten better, and most common distro's, are easier to use since, such as Zorin.
The requiring of password for common software installations and removals, is part of Linux's higher level of security, which you don't get on Windows. Windows chooses what you are going to do with your OS, and you have no control.
Infact, ever since Windows10 was a thing, I've heard countless reports of people angry, that Windows decided to update and restart itself, while they were working on an important document, and lost all the work.
Linux does not do this BTW. In Linux, you tell your OS what you want it to do, you tell it when to install updates, you tell it when to restart. And as far as terminal is concerned, I can also understand why that might be a bit daunting.
But you are also showing your age believe it or not, cause I remember in the 80's and early 90's, DOS was heavily used back in the days with Windows as well, and if you lived back then, you'd remember that.
And if you don't know what DOS is, well, strap your seat belts, cause guess what, its like Jonna and the whale, your going in. DOS is terminal, so you got to know the codes to make things happen.
So ya, while the terminal isn't really used in Windows anymore per say, it is in Linux, its a powerful tool once you know how to use it. I share your feelings though if you don't get the code exactly right, it throws up error.
So yes, I know it can be a pain. But like anything new, its a learning experience. And when it comes to the pure awesomeness of Linux, learning it is worth the time. So anyways, thats my take as a Linux user for 6-years now.
Still, if I need a ping I go straight for the CMD.
