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
