Can I still use my Chromebook now it is no longer supported?

Bill's Acer Chromebook C720 will not receive further updates. It works well so can he still use it?

I have recently got the message that my Acer Chromebook C720 will not be receiving any further updates as Google no longer supports Chromebooks older than six years. I use mine for surfing the internet, email and creating documents, which I send as email attachments. The machine still works as well as when I first bought it, and I'm reluctant to dump it for a new one.

I understand that I can install a new operating system myself but I really can't be bothered. The reason I bought a Chromebook in the first place was because of ease of use, simplicity and reliability. What are the risks if I just continue to use it without receiving any more updates? Bill

There is no way to assess the risk because it depends partly on what you use your Chromebook for, and how careful you are. Nowadays, most attacks require some kind of user assistance. This can mean, among other things, installing fake Android apps with hidden features, installing bogus Chrome extensions, visiting malicious websites, falling for phishing attacks, falling for man-in-the-middle attacks and failing to install essential security updates.
