Paul has an HP Stream, and he can't update Windows 10. Leo says that's because there's no real storage on it, with a 32GB hard drive. They want to compete with Chromebooks, but people can't do anything with them. As such, you can't really update them. You could install Linux on it. Leo recommends Linux MINT; it uses Ubuntu. There's also PopOS by System76 and Manjaro.
Mike finally installed Linux Mint into his old Dell laptop. When he was partitioning it, Windows wanted 2/3 of the drive for XP. He's not planning on using it that much, so he made it as small as he could, but it won't let him. Leo says he doesn't even need Windows if he's not planning on using it, so he can just delete the Windows partition altogether.
Chris heard that Linux got its Mint site hacked. Is Mint secure? Leo says that it was hacked and users could have been redirected to a corrupt operating system. Linux knows about it and they immediately fixed the issue and users should verify the ISO with an MD5 hash verification system or redownload the ISO with the fixed copy.
Camden is having issues with his Dell XPS' Wi-Fi connection. He's running Windows 7. Leo says to make sure Camden has the right driver from Dell. This would be the motherboard drivers, because most modern laptops don't have a separate card for it anymore. Leo has seen this happen with his Windows 10 Dell XPS 13, and he'd have to reboot for the Wi-Fi to come back. But when Leo uses Linux Mint with the Broadcom driver, he never has any issues.
Anthony wants to increase the RAM in his laptop. Leo says that he can do that with a special SO DIMM RAM, but he'll need to find out if he can. He can go to iFixit and look it up with their online manuals. Once done, he can go to either Kingston.com or Crucial.com and use the RAM picker to find out what RAM he'll need for it.
