Are you considering installing Chrome OS on your PC? Chromium OS (or Chrome OS) is a lightweight, open-source operating system developed by Google for their Chromebook line of personal computers. Chrome OS is a cloud-based OS that demands less hardware compared to other operating systems. Installing Chrome OS on an old PC or laptop can rejuvenate its performance. Fortunately, Google offers Chrome OS Flex, an official Chrome OS distribution designed for installation on Windows PCs, Macs, and Linux computers. The only difference between Chrome OS on Chromebooks and Chrome OS Flex is the absence of the Google Play Store, and you can't install Android apps on it. This Mytour guide walks you through the process of installing Chrome OS Flex on your PC.
