Finish browser security updates, including the restart

In brief

A browser can download an update while an older running process remains open. Complete the relaunch step and check the version afterward instead of trusting an update notification alone.

This is especially important on a computer that stays open for days and handles account sign-ins or work files.

Use the built-in update route

Desktop Chrome’s About page reports its installed version and update state. On mobile, use the official app store update route. Other browsers have their own supported update screens. Never install a “required browser update” offered by an advert or an unexpected webpage.

Check a failure rather than ignoring it

If the update repeatedly fails, record the error and inspect disk space, managed-device restrictions and OS support through the browser’s official help. Work computers may be controlled by an administrator; do not bypass that policy with a separate installer.

Review the remaining exposure

After the restart, check extensions and site permissions if suspicious behaviour remains. Password theft, an account session and an installed extension are not undone simply by installing a patched browser. Apply the appropriate account or extension recovery steps separately.

What to do next

1. Save unfinished forms and work before restarting.
2. In desktop Chrome, open Help → About Google Chrome and let the official update check complete.
3. Relaunch when prompted, return to the version page and inspect any update failure message.
