How to Update the Operating System on Chromebook

Install the latest OS version to get security patches and performance fixes.

Last verified: February 21, 2026

Chrome OS updates silently and automatically in the background while you use the device, downloading the new version without interrupting your work and applying it on the next restart — this is one of the most friction-free update experiences of any operating system. The OS uses a dual-partition system where the update installs to the inactive partition while you continue working on the current version, so the update is already complete before you even restart. Checking Settings > About Chrome OS > Check for Updates confirms you have the latest version, and Chrome OS devices typically receive updates for at least 10 years from release under Google's Automatic Update Expiration (AUE) extension policy.

Quick Steps

Follow in order for the fastest result.

  1. 1Click the system clock area, open Settings, scroll to About ChromeOS, and click Check for Updates.
  2. 2Connect to Wi-Fi and plug into power before starting a major update.
  3. 3After restart, check Settings > About for the new OS version number to confirm the update was applied.

Frequently Asked Questions

Why is my Chromebook OS update taking so long?
OS update speed depends on download size, your internet speed, and server load on release day. Keep the device plugged in and connected to Wi-Fi throughout.
Is it safe to use my Chromebook while an OS update is downloading?
Downloading is safe to continue using the device. The actual installation phase (after download completes) requires restarting and you must not interrupt it. Install updates when you can afford 15–60 minutes of downtime.
What happens if I don't update my Chromebook OS?
Security vulnerabilities accumulate over time. Operating systems receive regular security patches that close exploits discovered after launch. Running an outdated OS leaves those holes unpatched. After Microsoft or Apple end support for a version, no further patches are issued — at that point the OS becomes genuinely risky for internet use.
Why does my Chromebook say it's up to date but others have a newer version?
OS updates are typically rolled out in batches rather than to all devices simultaneously. Check manually in Settings and try again in 24–48 hours if nothing is shown.
