Linux

If you mean "dumb friendly" by "An exact Windows clone"... there are plenty of "Windowslike" Linux distros out there.

If you mean "user friendly" by "Easy to understand by any user"... then yes, (any) Linux distro is user friendly as is.

If the PC you're building has the latest and greatest hardware in it, you might find that Linux might not support that stuff yet. You might get lucky, but you might not either. It usually takes a little while to get new hardware supported. So it might be a better idea to install Linux on your older computer, then there's no reason to buy a new PC anyway. Linux uses about half the RAM that Windows uses, for example, so it's like you did an upgrade anyway. As long as you have over 4 GB of RAM, you're fine for desktop usage. Windows requires 8 to run as well that Linux does at 4. You'd only need to upgrade if you're after extreme gaming support.

To me, Endless OS seems to be the best fit for you; install it once and you never ever have to give it a second glance for troubleshooting or whatsoever. It achieves this through using "a read-only root file system managed by OSTree with apps installed using Flatpak.". This translates to:

• The most important system-related files being protected from change by yourself and others.
• Ensurance that your base installation is exactly the same as the one tested and used by its developers. And thus an (in-)direct quality control and maintenance by the very people that work on it.
• As the base system is not changing beyond what is provided by the devs, installation of applications is relegated to flatpaks (see Flathub for the App Store).
  • Flatpak is a packaging format that doesn't interact with the base system to install software; think of it like how applications are installed on your phone. With this, you can still install software you need without compromising changes to the base system.

I would say dual boot so you can use windows when you can't figure something out

If you decide yes, I highly recommend Fedora Silverblue, or any of the distros based on silverblue/ublue. I myself love Bazzite for gaming.

Those are atomic and immutable, meaning you cannot easily break core files, and every single thing can be updated in the app store. It's the windows equivalent of not being able to modify/delete C:\Windows; and getting firmware, drivers, applications, and Windows updates all in one click using the Microsoft Store.

It depends! You'll get a lot of recommendations. And they're probably good recommendations. But there are most certainly Distros out there that are very simple. I would suggest you don't be afraid to Distro Hop until you find one that you really feel at home on.

If you're looking for something that's simple, out of the box, and out of your way, I'd avoid anything Arch based. Ubuntu or Debian based Distros will have the most documentation and therefore minimize the amount of time you spend looking for answers, however, Fedora based Distros, in my experience, are rock solid and sit comfortably between stable and the bleeding edge.

I find that people who come from the old days of linux will often respond "you have to use terminal", or "learn the operating system", or even balk at people saying you can just use the GUI Interface/Desktop Environments. And then when you get help from expirienced users you get allot of terminal commands, which makes people think "I can't use Linux without learning the terminal first". In actuality it is just easier to show a person a command and ask for the results than it is to walk a person through getting the same info otherwise.

"OK, which Desktop Environment are you using?".

"Desktop what?".

"Which version of OS did you download and install?".

"Cinnamon.".

"X or Wayland?".

"What's a Wayland?".

"OK, X. Is your system up to date and which kernel are you running?".

...and so on. It is faster to just help working in the terminal. The Desktop Environments are fairly far along and most that I have worked with you could get by completely in the Desktop and not touch the terminal.

I would suggest Linux Mint, but for now I would stick to the non latest version of 21.3 as they bit off ALLOT in 22 and while it works for allot of people there are driver bugs they inherited from Ubuntu and have not implemented the fix for yet and allot of other pains in the toukus so if you want a version with the minimum of troubleshooting and stable Desktop Environments I would stick to 21.3 (If I had any sense I would be switching back to it from 22 myself).

If you want another option it would be Ubuntu and its Different Desktop 'Spins' to see which you like the most. Some people prefer to start off on Fedora and I am told it has a good DE, or some people recommend PopOS which had its own spin on a DE but they have let development lag on it as they developed their Cosmic Desktop for the Wayland project (the project that is superseding the X.org project for making windows).

Which ever you choose, good luck. I am in the same boat and I am trying to learn what I can before it is too late.

You should be fine doing what you want on Linux. Just make sure everything works before installing completely. There is a liveUSB mode that let's you try it before you install.

Mint and PoP os are good ones to try.

Can also check out Zorin os which is pretty good too but doesn't update as often.

You can absolutely get by by, and have a great experience with GNOME + the app store.

Its a reason its default on so many distros.

Simple Answer: No

The moment you need to think about what distribution you need to choose from is where it'll stop any (dumb)user. Most people want a simple process with very little thinking.

If you are interested in learning linux and willing to take the time to understand the entire process that comes with it then yes.

If you pick a new user-friendly distro, nine times out of ten it'll run like a dream out of the box.

If you want to change something minor like a desktop background, you might need to search through menus for the settings or ask for advice.

If you want to install new hardware, like swapping in a new video card, you'll definitely need some assistance.
