Chrome OS: Managing Auto Updates

New versions of Chrome OS are released regularly and tested by CAI to ensure no new features pose a risk for online testing. However, bugs or unintentional features do sometimes show up in the latest release. Because of this, CAI recommends disabling Chrome OS auto-updates or limiting auto updates to a version used successfully before summative testing begins to ensure Chromebooks remain stable during the test window. Chrome OS updates can be disabled or limited through the Device Settings page on the Chromebook. From this page, auto updates can be stopped or allowed, but only to a specific version.
