Checking your computer's system information — CPU, memory, storage, network, graphics, and operating system details — does not require digging through settings menus or running complex commands. Both Windows and Mac have built-in tools that surface all the key system specs in seconds, and you can access them through a handful of simple methods.
This guide walks you through The Quick System Information Method — a twelve-step approach that covers every way to view system information on both Windows and Mac, from native apps and dialogs to command-line shortcuts and third-party monitors. By the end, you will know exactly where to look on either platform to get a complete picture of your system in moments.
Quick tip: The fastest method on both platforms is a keyboard shortcut — Windows has the Run dialog, and Mac has About This Mac. Both open in under two seconds.
Step-by-step
Step 1: Step 1: Open the System Information App on Windows
The most complete way to view system information on Windows is the System Information app (msinfo32). Press the Windows key, type "System Information" in the search bar, and click the app to open it. A single window appears showing your processor, memory, hardware, and OS details all in one place. This is the go-to tool when you need a comprehensive overview of your Windows system in one view.
Step 2: Step 2: Use the Run Dialog to Launch System Info
For the fastest access on Windows, use the Run dialog. Press Windows + R to open it, type msinfo32 in the box, and press Enter. The System Information window opens instantly — no menus to navigate, no search bar to type through. This shortcut is ideal when you need system details quickly and already know the command.
Step 3: Step 3: Check System Info via Command Prompt
Windows also lets you pull system information straight from the Command Prompt or PowerShell. Open Command Prompt, type systeminfo, and press Enter. The command returns a detailed text report covering your OS version, processor, memory, network configuration, and more. This method is especially useful when you need to capture system details for troubleshooting or sharing, since you can easily copy the output as text.
Step 4: Step 4: Open About This Mac on Mac
On Mac, the quickest way to view system information is the About This Mac window. Click the Apple menu in the top-left corner, select About This Mac, and a compact window appears showing your Mac model, chip, memory, storage, and macOS version. This is the Mac equivalent of Windows' System Information app — fast, built-in, and covering the essentials at a glance.
Step 5: Step 5: Use System Settings for System Details
For a deeper look on Mac, open System Settings (or System Preferences on older macOS versions). Click About This Mac, then explore the tabs for more detail. You can also open Activity Monitor to see live CPU, memory, energy, disk, and network usage. System Settings gives you a more structured, detailed view of your system and is the right choice when you need to understand how your Mac is currently performing, not just its specs.
Step 6: Step 6: Review CPU and Memory Usage
Once you have the system information window open, focus on the CPU and memory sections. On Windows, the System Information app and Task Manager both show your processor model and RAM capacity. On Mac, About This Mac and Activity Monitor display the chip and memory details, along with current usage. Checking these two metrics regularly helps you understand whether your system has enough power for the tasks you run and whether memory is becoming a bottleneck.
Step 7: Step 7: Check Storage and Disk Space
System information is not just about the processor and RAM — storage matters too. On Windows, open This PC or File Explorer to see your drive capacities and free space, and use the Disk Management tool for detailed partition info. On Mac, open About This Mac and click Storage to see your disk capacity, or use Disk Utility for a detailed breakdown. Knowing how much storage you have and how much is free helps you plan ahead before space runs out.
Step 8: Step 8: Inspect Network and Connectivity Info
Your system's network configuration is another key piece of system information. On Windows, open Settings > Network & Internet or use the ipconfig command in Command Prompt to see your IP address, subnet mask, and DNS settings. On Mac, open System Settings > Network or use the Network Utility app to view connection details, IP address, and routing information. This step is essential when troubleshooting connectivity or verifying your network setup.
Step 9: Step 9: View Graphics and Display Details
Graphics and display information is important for understanding what your system can handle visually. On Windows, open Settings > Display or use the DirectX Diagnostic Tool (dxdiag) to see your GPU model, display resolution, and driver details. On Mac, the About This Mac window and System Settings > Displays show your graphics capabilities. Checking these details helps when you need to verify display settings or troubleshoot graphics-related issues.
Step 10: Step 10: Check Your OS Version and Updates
Your operating system version is fundamental system information that affects compatibility, security, and features. On Windows, open Settings > System > About or use the winver command to see your exact Windows edition and build number. On Mac, the About This Mac window shows your macOS version. Regularly checking your OS version and staying current with updates ensures your system remains secure and compatible with the latest software.
Step 11: Step 11: Export or Share System Information
Sometimes you need to share or save system information for troubleshooting or reference. On Windows, the System Information app allows you to save a report file, and the systeminfo command output can be redirected to a text file using a simple command. On Mac, you can capture the About This Mac details or use the system_profiler command to generate a text report. Having a saved copy of your system information makes it easy to reference or share with technical support.
Step 12: Step 12: Use Third-Party System Monitors
If you want a real-time, always-visible view of your system, consider a third-party system monitor. Tools like HWMonitor, CPU-Z, or MSI Afterburner on Windows, and iStat Menus or Stats on Mac, provide live dashboards showing CPU temperature, usage, memory, and other metrics in your menu bar or taskbar. These tools complement the built-in methods by giving you an at-a-glance, real-time view that updates continuously — perfect for monitoring system health over time.
Final Thoughts: Viewing system information on Windows and Mac does not have to be a complicated process. By using the built-in tools each platform provides — the System Information app and Run dialog on Windows, About This Mac and System Settings on Mac — you can access all the key system details in seconds. For deeper or real-time monitoring, command-line tools and third-party monitors fill in the gaps. The key is knowing which method to reach for based on what you need: a quick overview, a detailed report, or a live performance readout. With these twelve steps, you will never have to hunt through settings to find your system information again.
