Check Operating System Version + How to Update Safely (Quick Tool)

Not sure what operating system you’re using — or whether it’s time to update? This quick tool helps you check operating system version on Windows, macOS, iPhone/iPad (iOS/iPadOS) and Android, then shows the safest place to confirm it in your Settings/About screen. A current OS helps keep your device secure, stable, and compatible with websites and apps — and this checker runs locally in your browser (no installs, no sign-up).


Check Operating System Version (& Web Browser)

Quickly see what browser and operating system you’re using — plus the simplest steps to update safely.

  • Privacy-first (runs on your device)
  • Fast & free
  • Best-effort detection (some browsers hide details)

Click “Run check” to see your results.

Some browsers hide OS details for privacy. If anything shows as “hidden”, use your system “About” screen to confirm.

What to do next

Ready
Theme Stay secure and compatible
Action Update browser first, then OS
Outcome Fewer security risks and fewer “this site/app won’t work” issues
  1. Update your browser first (it’s the front door to your accounts).
  2. Update your OS next (it patches deeper security issues).
  3. Restart after updates — many fixes apply only after a reboot.
If updates are blocked (work/school devices)
  • If you see “Managed by your organisation”, you may need IT to approve updates.
  • Ask whether your device is in an “update ring” and when the next patch window is.
  • For personal devices, ensure you’re using an administrator account to apply updates.

This tool uses a “soft check”: the most reliable confirmation is the browser “About” page (it triggers an update check).

If these fields look sparse, your browser is simply sharing less data for privacy (normal behaviour).
