Frequently Asked Questions
What is a user agent?
A user agent is a string your browser sends to websites identifying itself. It includes browser name, version, and operating system.
Can user agents be faked?

Why does my browser show a different OS version?
Some browsers freeze or cap OS version numbers in user agents for privacy reasons. For example, Chrome may show Windows 10 even on Windows 11.
