It sounds like your computer is on its last legs and your parents are computer illiterate/indifferent. Best case they just won’t use the computer. Worst case they’ll blame the computer kicking the bucket on your linuxing. I keep getting nudged into tech-supporting my MIL. She had a very aging Windows 8 laptop set up in a language I don’t speak that well. Also I haven’t used Windows for almost 30 years. What could possibly… We bought her mid-range Chromebook and haven’t had any issues for two years.
