Linux

Based on your last paragraph, you might fall in the supernoob catergory. You'll want an immutable distribution, you can't break those Unless you tell it to let you break it.

As a windows user, you'll find familiarity in Fedora Kionite.

If you prefer a touchscreen oriented experience consider Fedora Silverblue.

There's a few other options on the page I'm linking, I haven't tried and therefore can't recommend either of the others.

Edit 2, electric boogaloo:

OP in your post you state you want Wallpaper Engine to work, unfortunately, you'll have issues there. Depending on what you're trying to accomplish with wallpaper engine you may be able to do the same using KDE Plasma. I personally use a VLC command line call to enable animated wallpapers on my rig, there's not exactly a standard for it on Linux so many of the solutions you find will be clunky. Just remember if you go around messing with your xorg.conf file you need to have a backup of it so you can undo changes easily in a terminal.

You're welcome to DM me if you need assistance.
