Device information is not a full hardware inventory

Logical processor counts and device-memory hints may be rounded or hidden by the browser. OS versions in the User Agent may be frozen. This page cannot read device serial numbers, full memory specifications or all installed software.

How screen and language affect a fingerprint

Window zoom, external displays, pixel ratio and system language affect the values a page sees. Record window size and zoom when testing. A resolution change does not automatically mean a different device.

Frequently asked questions

Why is memory or platform information unavailable?

Browsers expose different APIs and may restrict values for privacy. Unavailable does not mean the hardware is faulty.

Can this identify Windows 10 and 11 exactly?

The User Agent alone cannot reliably distinguish them. Supported Client Hints may provide additional information, but remain browser-supplied claims.
