I suggest creating an admin account and a separate "guest user" account.
Once you've installed:
OpenSUSE Leap: If you encounter problems connecting to the internet, there is a file to remove named 'resolv.conf'; after removing that file I was able to connect to the internet without issues. To remove it, open Konsole terminal and type the following:
sudo -i press Enter (enter your admin password) <<---- this logs you in as 'root'
cd /run/netconfig/
rm resolv.conf
logout
Then restart the machine and you should be able to connect to the internet. By, the way I searched something like: "can't connect to internet on OpenSUSE" and found this solution .. that's how I move forward in learning Linux.
To update your OS (daily)
Ubuntu, Xubuntu, Lubuntu: Ctrl-Alt-T to bring up terminal, type sudo apt update (enter admin PW), then sudo apt upgrade and confirm y for yes ..
Fedora: sudo dnf uptade; sudo dnf upgrade
