Section CXLIX.Configuring Chrome OSThis section describes how to configure auto-updates to Chrome OS. Section CL.Disabling Auto-Updates for Chrome OSBecause AIR supports Chrome OS up to a specific version, you may want to disable auto-updates. For example, if AIR supports up to Chrome OS version 46, and version 46 is installed on your Chromebooks, you can prevent auto-updates to any later version. (Alternatively, you can allow auto-updates to a specific version supported by AIR; for details, see the section Limiting Chrome OS Updates to a Specific Version.) To disable auto-updates for Chrome OS: Section CLI.Display the Device Settings page by following the procedure in Manage device settings, https://support.google.com/chrome/a/answer/1375678?hl=en. The steps in that procedure assume that your Chromebooks are managed through the admin console.
Section CLII.Limiting Chrome OS Updates to a Specific VersionBecause AIR supports Chrome OS up to a specific version, you may want to prevent your Chromebooks from auto-updating beyond that version. For example, if AIR supports up to Chrome OS version 46, and version 45 is installed on your Chromebooks, you can allow auto-updates up to version 46, and prevent auto-updates to any later version. (Alternatively, you can disable auto-updates entirely; for details, see the section Disabling Auto-Updates for Chrome OS.) To limit Chrome OS updates to a specific version: Section CLIII.Display the Device Settings page by following the procedure in Manage device settings, https://support.google.com/chrome/a/answer/1375678?hl=en.

Section CLIV.Installing CloudReady on PCs and MacsCloudReady is a reduced-feature operating system, built on the same technology as Chrome OS, that runs on hardware with limited resources.

This installation can postpone or prevent a costly hardware upgrade.
