I once get told to buy a new laptop, see the specifications displayed as having Windows 10, but when booted up for test, surprise surprise, the installed OS was Ubuntu lmao
Unfortunately it was for a coworker, and they're not quite tech savvy, and thus requested for Windows...
I forgot, it's lesser known and maybe just a local brand, definitely not the big names like Lenovo, Acer, or Asus. It was cheap laptop, our workplace is stingy as hell
