About ChromeOS Update

The ChromeOS update screen with the light surface design, Chrome-colored dot spinner, and 'Almost done' messaging. Matches the current Chromebook update experience.

Fake ChromeOS Update for Chromebooks

The ChromeOS update screen features Google's Material Design language — light surface, the multicolored Chrome dot spinner, and the characteristic 'Almost done' messaging. Chromebooks are ubiquitous in schools, making this prank especially effective in educational environments. The design matches the current ChromeOS update experience closely enough to fool students and teachers alike.

School and Education Pranks

Chromebooks dominate the US K-12 education market. This fake update screen is perfect for classroom pranks — open it fullscreen on a classmate's Chromebook during a free period. The Chrome-branded spinner and clean Google design language are instantly familiar to students. Teachers can also use it as a lighthearted way to start a class.

Pro Tip: Chromebook Specificity

This prank only works on Chromebooks or when displayed on a Chrome browser. The ChromeOS visual language is distinct from Windows or macOS, so use it on the correct platform for maximum believability.

Frequently asked

The shortest path between you and the answer.

Is this tool free?

Yes. Every ScreenTools.co tool is free, with no account, no paywall, and no install.

Does it work on mobile?

Yes. Layouts adapt to phone and tablet screens. Mobile Safari restricts true fullscreen, but the page fills the viewport and you can add the page to your Home Screen for an app-like experience.

Does it work offline?

Once a tool's page has loaded once, the runtime is local. A few tools that fetch fonts or icons need the first hit online; after that, refresh works offline.

Does this collect my data?

No personal data leaves your browser. The site has lightweight, privacy-respecting analytics for aggregate counts (which tool was opened) and nothing else.
