How can I see system information about my PC?
When people search for system information, about my PC, about this computer or computer specs, they usually want a quick summary of the device they are currently using. That includes your operating system, browser, screen resolution, hardware details and other technical signals. This page shows key device specifications at the top, along with a deeper breakdown of your computer information below.
What system information and specifications can a website see?
A website can automatically detect certain system information and device specs that your browser shares, such as your browser type, operating system, language, screen size, timezone, estimated location and (on the server side) your public IP address. Some PC specs and device specifications are intentionally limited for privacy reasons, so websites cannot reliably see your exact processor model, exact RAM size or a unique device ID.
Where can I check full computer specs or information about this computer?
For more detailed computer specs or advanced system details, you can use the built-in System Information tool in Windows or the “About This Mac” section on macOS. This website focuses on the device information that websites can detect through your browser, not the complete hardware profile stored locally on your computer.
Device info vs device name vs device model
Device name is usually what you set in your settings (like “John’s iPhone”) — websites typically cannot read that. Device model (like “Pixel 7” or “SM-G991B”) is sometimes available on certain browsers via client hints, but is often blank or masked. For many devices (especially Apple devices), the browser intentionally hides exact model details.
What is my device ID?
People sometimes search for a device ID, but modern browsers do not provide a simple “device ID” to websites. That’s a privacy feature. Websites can still recognize you in other ways (cookies, local storage, login sessions, or fingerprinting), but there is usually no single official “device ID” exposed through the browser.
How to find or track your device (official methods)
- iPhone / iPad: Use Apple Find My to locate, play a sound, mark lost, or erase.
- Android: Use Google Find My Device to locate, ring, lock, or erase.
- Windows: Windows “Find my device” can show last known location if enabled.
- Mac: Use Apple Find My if it was enabled on the Mac.
If your device is stolen: change important passwords, contact your carrier, and report it to local authorities.
How to check system information in Windows
If you want to see full system information or detailed PC specs directly in Windows, you can use built-in tools:
Method 1: System Information tool
- Press Windows + R.
- Type msinfo32 and press Enter.
- You’ll see detailed computer information including processor, RAM, BIOS version and more.
Method 2: About this PC
- Open Settings.
- Go to System → About.
- This shows basic device specifications such as processor, installed RAM and system type.
How to check computer specs on Mac
- Click the Apple menu in the top-left corner.
- Select About This Mac.
- Here you can see your Mac model, processor, memory and macOS version.

What is my operating system?
Your operating system (OS) is the main software that runs your device — such as Windows, macOS, Linux, Android or iOS. This page automatically detects your OS based on browser signals and displays it at the top.
Knowing your operating system is important for installing compatible software, troubleshooting problems, and checking system requirements.
Can websites see my full computer specs?
No. Websites can only access limited device specifications that your browser exposes. They cannot directly read your full hardware profile, installed programs, serial numbers or private files.
Modern browsers intentionally restrict detailed PC specs to protect your privacy.
