Get Linux Cinnamon Mint. It will operate very similar to windows. If your computer has Uefi boot use Version 20 or higher. If it does legacy boot you will need version 19.3.
Thanks...UEFI boot?
Not in my experience, in comparison with much customized Windows. Tried many Linux distros, besides Mint, and the best I have found so for *for me) is PclinuxOS, KDE. Among other options, it is the only one I used that actually enables remapping the CapsLock key to ctrl+c (not just ctrl), without even needing to code anything. Can't get multi-level taskbar yet. Just a small-time hobby. Thank God for options to do good with. I do not knowingly install proprietary codecs though.
