ChromeOS Flex can bring new life to an old PC that isn't receiving security updates anymore.
Eventually, your aging computer will no longer receive new security patches. Windows 10 reached its end of life in October 2025, though extended security updates are still offered through October 2027. Older Macs will reach end-of-life status before long too; with macOS 27 dropping support for Intel Macs, security patches will only last as long as macOS 26 is supported.
Even if your old computer feels slow, an alternative operating system like Google's ChromeOS might be all you need to make it useful again. ChromeOS needs fewer resources than Windows and typically offers a smoother experience on lower-end computers.
Historically, the only way to access ChromeOS was to buy a Chromebook with it pre-installed. The process only takes about an hour, and you may already have everything you need to get started.
ChromeOS Flex needs an Intel or AMD CPU, 4GB of RAM and 16GB of storage. The age of the hardware matters too, since CPUs from 2012 or earlier don't support newer ChromeOS versions. Those are relatively modest requirements when compared to Windows 11.
You must have an existing computer with Chrome installed to create the installation media.
After you've gathered everything you need, open Chrome and install the Chromebook Recovery Utility extension. Click Get started, then select Google ChromeOS Flex in the dropdown menus on the next page, followed by Continue.
While ChromeOS Flex can extend the life of your device after Windows or macOS updates end, you can't expect its support to last forever.
