If you or someone you know is still running Windows 7 on a device connected to the internet then it's time to upgrade, today (14th January 2020) is the end of extended support. This means no more security updates, you will be vulnerable if you don't move on. It's the perfect time to try a Linux distro like Ubuntu, Fedora, Linux Mint or Manjaro a try, or the simpler option just move on to Windows 10.
