Google says ChromeOS will get updates and security patches through mid-2034.
In an FAQ for IT administrators about Googlebook OS, its new operating system built on the Android tech stack, Google says ChromeOS devices will keep receiving regular updates and security patches through mid-2034. Current Chromebooks keep getting updates for their supported lifetime under Google's Auto Update policy, and many newer models will be able to move to Googlebook OS. Google says Googlebooks are for personal use for now, with management tools for businesses and schools starting to roll out in the second half of 2027.
Why it matters: If you're buying Chromebooks for staff, check each model's Auto Update date. ChromeOS updates end in mid-2034; for qualifying devices supported beyond that, Google says it will support a move to Googlebook OS.
