About the system information tool
This tool collects everything your browser is willing to reveal about its environment — user agent, platform, language, screen geometry, pixel ratio, approximate CPU thread and memory hints, and connection type — and lays it out on one readable page. It is the fastest way to answer "what exactly am I running?" from inside a browser.
Browsers deliberately blur some of this information to protect you from fingerprinting, so missing or rounded values are a privacy feature, not a fault. What remains is still exactly what a support technician, an IT helpdesk or a bug report usually needs: which browser and version, which platform, what screen, and whether the API a failing feature depends on is supported at all.
Reading the page costs nothing and changes nothing — it only displays what the browser already exposes to every site you visit. Copy the summary when you file a support ticket, and share only what is relevant: browser, OS and screen details are usually enough.
What the system information means
This tool shows information your browser is allowed to reveal. It is useful when explaining a problem to support, comparing browsers or checking why a feature may be unavailable.
What this test checks
- Browser user agent, language, platform and cookie/storage support.
- Screen and viewport details including pixel ratio and orientation.
- Approximate hardware hints such as CPU threads and device memory where supported.
- Connection hints such as effective connection type and reduced-data preference when exposed by the browser.
How to understand your results
- A good result is not a pass/fail score. It is a reference sheet for troubleshooting.
- Missing values are normal. Browsers deliberately limit some details for privacy and fingerprinting protection.
- If camera, microphone, gamepad or Wake Lock features are unavailable, system info can reveal whether the browser supports the needed API.
- Share only what is relevant. User agent and screen details are usually enough for support; avoid posting sensitive information publicly.
Common problems and fixes
Hardware details missing
Safari, Firefox and privacy-focused browsers may hide memory, CPU or connection hints. That is expected.
Wrong platform shown
Some browsers simplify or freeze platform strings. Use OS settings for authoritative device details.
Feature unsupported
Update the browser or try Chrome, Edge, Firefox or Safari depending on the API needed by the tool.
Support needs details
Copy the visible summary and include which tool failed, what you clicked and the exact error message.
FAQ
Does this reveal private files?
No. Browser pages cannot read your files or full system inventory without explicit file selection or permissions.
Why are some values approximate?
Modern browsers reduce hardware detail to protect privacy and reduce fingerprinting.
Can I use this for IT support?
Yes. It provides a quick browser-context summary that is useful alongside screenshots and error messages.
Why does it not show my exact CPU or RAM?
Browsers only expose rough hints — a thread count and a coarse memory band — because precise hardware details would make you easier to track across sites.
Is any of this information stored by the site?
No. The page reads the values in your browser and displays them locally; nothing is collected or saved by the server.
Why does every website seem to know my screen size?
Screen and browser details are part of what every page can read to lay itself out. This tool simply makes visible what is already available to any site you visit.
Browser-based test disclaimer
TestMyPC results are browser-based and may vary depending on your device, browser, operating system, permissions, drivers, connection, power settings and connected accessories. Use these tools as practical first checks, then confirm important faults with operating-system diagnostics, manufacturer tools or a qualified technician where needed.
