Might also want to consider a Linux distro. I recommend Pop_OS!
Discussion
I like Elementary OS or Fedora. Been using them for many years.
PopOS is so easy, my mom uses it. Great Windows alternative
Is it easy to install for regulsr people?
Yes, it's meant to be a good option for Windows users, to dip their toe in the Linux ecosystem without looking and feeling a lot different. You basically flash the .iso/.img file onto a USB, then boot up using the USB, and it walks you thru the install process
