I installed zorin on an old machine that was given to me because it wouldn’t run win 11. I like it a lot. Debian based, clean smooth UI. Just tell them Microsoft improved the user experience with windows 11.
Even the one major 'windows' app that my mom needs to use is going Web only... so I figure if I install Debian Stable + Widevine that'll cover 99.9% of the use case and I gain an OS that just works correctly.
