What Operating System Do I Have?
This page names the operating system your browser is running on — Windows, macOS, Linux, ChromeOS, Android, or iOS — along with whatever version information your browser is willing to share. It is the fastest answer when a download page asks you to pick a build, when support asks what you are running, or when you are checking whether a device is on the version an app requires. Detection is read from what your browser reports about itself, so it takes no permission, no install, and no account. Bear in mind that browsers now deliberately blur these details to reduce fingerprinting: modern versions of Windows and macOS often report a frozen or rounded version number, so treat the version as approximate and check your system settings when the exact build matters.

Browsers deliberately blur these details to reduce fingerprinting, so treat the version as a hint. Where a browser publishes nothing — which is every non-Chromium browser for architecture — this page says so instead of guessing.
How to use the what operating system do i have
- Open the page — your operating system is detected and shown immediately.
- Read the version line, remembering that browsers deliberately round or freeze it.
- Use it to pick the right download or to fill in a support request.
- Open your system settings if you need the exact build number.
Frequently asked questions
- Why is the version wrong or missing?
- Browsers have been reducing what they disclose to limit fingerprinting. Windows 11 is often reported as Windows 10, and macOS frequently reports a frozen version. The operating system family is reliable; the version is a hint.
- How is my operating system detected?
- From the information your browser publishes about its platform, including the user agent string and, in Chromium browsers, user agent client hints. Nothing is installed and no files are read.
- Can this tell 32-bit from 64-bit?
- Sometimes. Some browsers expose the architecture through client hints, but many do not. When it is unavailable the page will not guess.
- Does it work on phones and tablets?
- Yes. Android and iOS are detected the same way. Note that iPads request desktop sites by default, so an iPad often identifies itself as macOS.
