Checkout Bluefin (or Bazzite if you're more into games). They do a pretty good work at making you not need to know anything about Linux to use it well.

Unless you happen to need some uncommon driver or software, you can "just use" it.

I felt the exact same way, still do, but I bought a new drive and installed Linux Mint on it (it's the most Windows like experience I've found). I kept my old windows drive just in case, but I haven't needed it so far.

The only time I ever used something that wasn't Windows was DOS when I was very little.

It's definitely overwhelming when trying to get certain things working that aren't natively supported, but thankfully those are few and far between. There's also a lot of people in the Linux community that are passionate about it, and tend to be very helpful.

You can always download what I think is called a live distro, and run it off a thumb drive just to test the waters. Nothing you change will be kept though, and it will be sluggish comparatively.

What's wrong with Windows?

The better question is why Linux over something you know how to use. Both systems have there own issues.

The os itself doesn't require a whole lot of learning, if you stick to something user friendly like mint cinnamon. Key differences are how you install programs and drivers. File structure is very different. After two years of daily driving mint cinnamon, I find it more difficult to do basic stuff in windows, especially 11. If it feels intimidating, the recommended approach is to try it out on another pc, dualboot, or use it in a virtual machine.

Go for it. You don't need to install Linux in order to start getting your feet wet. Get a USB 3.0+ flash drive and put a "live" (CD/USB, whatever the distro wants to call it) distro on there. There are plenty of directions out there on how to make one from Windows. Most live distros nowadays are persistent, so any programs you install will be there next time you load it up. It will definitely be slower than a normal install, but it'll let you get a feel for how things work.

Go ham wild on there, break stuff, see if you can fix it, don't, then remake it again. Try different desktop environments (DEs) and see what you like. Your distro of choice is less important if you're just starting, but any of the big ones will be fine. I'd recommend trying a few different DEs from the same distro, see what you like the feel of, then try a different distro with what you liked best. They'll usually all have gnome, kde, and a third lightweight option, but in my experience if Wayland (the other choice is X11) works well, kde and gnome will feel pretty light. I use kde Wayland on this guy and trust me, this review is giving it a lot of grace. Windows 10 was completely unacceptable on it, so if your specs are any better then this, you'll be fine with whatever you choose. Beware that Nvidia cards have driver issues, they're fixable but if you do have an Nvidia card, I'd just use the built in graphics chip for trying out Linux at first.

Don't start with arch, btw.
