How to Use System Information to Find Your Computer Configuration

Some links on this page are affiliate links: if you buy through them we may earn a commission, at no extra cost to you.

The quickest way to find your computer’s basic configuration is Settings > System > About in Windows, Apple menu > System Settings > General > About on a Mac, or a combination of commands such as lscpu, lsblk, and free -h in Linux. For a complete inventory, use Windows System Information, macOS System Report, or several Linux hardware commands.

A full configuration record can include the computer model and serial number, operating-system version, processor, memory, graphics, storage, firmware, network adapters, and display. No single screen always shows every detail.

What “computer configuration” includes

Computer configuration is broader than a list of processor and RAM specifications. Depending on why you need it, record:

• Identity: manufacturer, model, device name, and serial number.
• Operating system: edition, version, build, distribution, kernel, and 32-bit or 64-bit architecture.
• Processor: model, cores, logical processors, and clock information.
• Memory: installed and usable RAM, speed, type, and populated slots.
• Graphics: integrated or discrete GPU, graphics memory, driver, and display resolution.
• Storage: drive model, capacity, interface, partitions, and free space.
• Firmware and connectivity: BIOS/UEFI, Wi-Fi, Ethernet, Bluetooth, and related adapters.

You may need this information to check software requirements, verify a refurbished computer, choose compatible RAM or storage, troubleshoot crashes and drivers, contact support, create an asset inventory, or prepare a device for sale.

Find your configuration in Windows

Quick method: Settings

1. Open Start > Settings.
2. Select System > About.
3. Review the device name, processor, installed RAM, system type, Windows edition, version, and build.

This is the fastest method for routine support, but it may not identify every drive, GPU detail, RAM module, motherboard, driver, or firmware setting.

Complete inventory: System Information

1. Press Windows + R.
2. Enter msinfo32 and press Enter.

For the most complete result, search for System Information from Start, right-click it, and choose Run as administrator. Microsoft notes that running MSINFO32 without elevation can cause some driver statuses to appear incorrectly, and hardware reporting is limited in Safe Mode. See Microsoft’s System Information documentation.

In the left pane, inspect:

• System Summary: Windows version, manufacturer, model, system type, processor, installed and available physical memory, BIOS mode, BIOS version and date, and Secure Boot state.
• Components: display adapters, storage, network, USB, sound, and input devices.
• Software Environment: drivers, services, startup programs, running tasks, and Windows error-reporting information.
• Hardware Resources: IRQs, conflicts, DMA, and other low-level assignments.

Export a Windows report

Create the destination folder first, then open an elevated Command Prompt and run:

mkdir C:Temp
msinfo32 /report C:TempSystemReport.txt
msinfo32 /nfo C:TempSystemReport.nfo

The /report switch creates a text report, while /nfo creates a native System Information file. Microsoft also documents /computer ComputerName for querying an authorized remote computer when permissions and remote WMI access are available.

Use Task Manager for live details

Press Ctrl + Shift + Esc, select Performance, and open the relevant panel:

• CPU: processor model, current speed, cores, logical processors, and virtualization status.
• Memory: installed memory, speed, slots used, form factor, and hardware-reserved memory.
• Disk: activity, capacity, and detected drive type.
• GPU: model, utilization, dedicated memory, shared memory, and driver information.
• Ethernet or Wi-Fi: link speed and network activity.

Task Manager shows current operating conditions, not a complete historical hardware report. Processor speed changes with workload, temperature, power limits, and boost behavior.

Check drivers and hardware IDs

Open Start > Device Manager. Useful categories include Display adapters, Processors, Disk drives, Network adapters, Bluetooth, Storage controllers, and System devices.

To identify a device more precisely, right-click it, choose Properties > Details, and select Hardware Ids or Device instance path. Device Manager is valuable for driver troubleshooting, but generic names, hidden devices, virtual adapters, and duplicate entries can make it unsuitable as the only configuration source.

Use PowerShell for structured output

Open PowerShell and run:

Get-ComputerInfo

For a shorter summary:

Get-ComputerInfo | Select-Object CsManufacturer, CsModel, CsSystemType, OsName, OsVersion, OsArchitecture, CsProcessors, CsTotalPhysicalMemory

Targeted hardware queries include:

Get-CimInstance Win32_Processor | Select-Object Name, NumberOfCores, NumberOfLogicalProcessors, MaxClockSpeed

Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, PartNumber, Capacity, Speed, ConfiguredClockSpeed

Get-CimInstance Win32_VideoController | Select-Object Name, AdapterRAM, DriverVersion

Get-CimInstance Win32_DiskDrive | Select-Object Model, SerialNumber, Size, MediaType, InterfaceType

Get-ComputerInfo returns a consolidated Windows system and operating-system object. Property names and values can vary by Windows release and hardware. AdapterRAM should not automatically be treated as the GPU’s actual usable VRAM, and Win32_DiskDrive describes physical disks rather than free space on logical volumes.

Find your configuration on a Mac

Quick method: About settings

1. Open the Apple menu.
2. Choose System Settings > General > About.
3. Review the Mac model, Apple silicon chip or Intel processor, memory, serial number, macOS version, displays, and storage.
4. Select System Report for detailed information.

On some macOS versions, the same summary is available through Apple menu > About This Mac. Click the macOS version number to reveal the exact build number. Apple’s About settings documentation describes the current labels.

Use System Report

Open Apple menu > System Settings > General > About > System Report. You can inspect hardware, storage, USB devices, displays, memory, power, network connections, operating-system data, applications, kernel extensions, software versions, and hardware identifiers. Apple also documents an alternative shortcut: hold Option while opening the Apple menu and choose System Information.

To save a report, open System Information and choose File > Save. Choose Show More Information for a fuller report or Show Less Information for a shorter one. A detailed report can be several megabytes and may contain sensitive network and software information.

Use macOS Terminal

These commands provide focused reports:

system_profiler SPHardwareDataType SPSoftwareDataType
system_profiler SPDisplaysDataType
system_profiler SPStorageDataType
system_profiler SPNetworkDataType

Save a useful text report to the desktop with:

system_profiler SPHardwareDataType SPSoftwareDataType SPDisplaysDataType SPStorageDataType > ~/Desktop/mac-system-report.txt

To display the serial number:

ioreg -l | grep IOPlatformSerialNumber

Apple documents this command as an option even when using Terminal from macOS Recovery.

Apple silicon Macs use unified memory shared by the CPU and GPU. Do not describe it as ordinary system RAM plus separate dedicated VRAM without qualification. Many newer Macs also have soldered memory and storage, so System Report alone cannot establish whether an upgrade is possible.

Find your configuration in Linux

Linux desktop paths differ by distribution and desktop environment. Try Settings > About, GNOME Settings > System > About, or KDE Info Center. Distribution utilities such as HardInfo may also be available, but the terminal is the most portable approach.

Core commands

uname -a
cat /etc/os-release
lscpu
free -h
lsblk -o NAME,SIZE,TYPE,FSTYPE,MOUNTPOINTS,MODEL
lspci
lspci | grep -Ei 'vga|3d|display'
lsusb
df -h

• uname -a shows kernel and system information.
• cat /etc/os-release identifies the Linux distribution and release.
• lscpu reports CPU architecture, cores, threads, and capabilities.
• free -h reports installed, used, and available memory in readable units.
• lsblk lists drives, partitions, mount points, and often drive models.
• lspci identifies PCI devices such as graphics and network controllers.
• lsusb lists connected USB devices.
• df -h shows free and used space on mounted filesystems.

For a deeper inventory, install the appropriate package if necessary and run:

sudo lshw -short
sudo lshw -html > hardware-report.html

Another optional summary tool is:

inxi -Fxxxz

The -z option attempts to sanitize identifying information before sharing output. Command availability and output vary by distribution. The lscpu, lsblk, lspci, free, uname, lshw, and inxi manuals explain their options.

How to interpret the results

CPU model, cores, threads, and speed

The CPU model and generation are more useful than a speed number alone. “Cores” are physical processing cores; “logical processors” or “threads” include simultaneous multithreading where supported. Reported speed may be a current, base, or maximum value and can change dynamically.

Installed versus usable RAM

Installed RAM is the physical memory fitted. Usable RAM is what the operating system can use after hardware reservations. Available RAM changes constantly as applications run. Integrated graphics may reserve or dynamically share system memory.

GPU memory

A GPU name does not always reveal VRAM. Dedicated graphics generally have physical graphics memory, while integrated graphics commonly use shared system RAM. Windows may show dedicated, shared, and total available graphics memory as separate figures.

Storage capacity versus free space

Capacity describes the size of a drive or volume; free space describes what remains available. The usable capacity shown by the operating system is normally lower than the advertised decimal capacity because manufacturers and operating systems use different unit conventions. “SSD” alone also does not prove whether the interface is SATA or NVMe.

Model numbers and upgrade decisions

Use the complete computer or motherboard model when checking RAM, storage, displays, docks, or replacement parts. Do not infer a maximum supported RAM capacity from a utility alone. Confirm the limit, slot type, form factor, storage interface, and physical clearance with the manufacturer or motherboard documentation.

If information is missing or looks wrong

• Windows: run System Information as administrator and regenerate the report. Do not treat a Safe Mode report as complete.
• macOS: try About settings, Terminal, or macOS Recovery if the desktop is unstable. Use Apple Diagnostics for suspected hardware faults rather than treating System Report as a health test.
• Linux: a command may be missing; install the relevant distribution package for pciutils, lshw, or inxi when appropriate.
• Hybrid graphics: laptops may list both integrated and discrete GPUs.
• Virtual machines, containers, and WSL: hardware visibility may be restricted or may show virtual hardware rather than the host computer.
• Non-booting systems: check the manufacturer’s firmware setup screen, chassis label, packaging, purchase record, or manufacturer account.

A configuration report identifies what the operating system detects. It does not prove that a drive, battery, GPU, or other component is healthy, nor is it a performance benchmark.

Share a system report safely

Before uploading or emailing a full report, remove or redact:

• Serial numbers and drive serial numbers.
• Device names, usernames, profile paths, and account names.
• IP addresses, MAC addresses, domain names, and organization names.
• Product keys or activation details.
• Installed applications, work-related file paths, and other sensitive software information.

Mac System Report can include network information, IP addresses, applications, and software locations. Windows and Linux reports can also expose identifying paths and device details.

When third-party tools are worthwhile

Built-in tools are sufficient for most configuration checks and avoid unnecessary downloads. Use a reputable third-party utility only when you need deeper RAM-module data, motherboard details, sensors, PCI information, storage interfaces, or a simpler consolidated report.

• HWiNFO provides detailed Windows hardware analysis, monitoring, and reporting. Its licensing page says free versions are intended for personal, non-commercial use; check current terms before commercial use.
• CPU-Z is a Windows freeware utility focused on processor, motherboard, memory, and SPD information.
• Speccy provides a simpler Windows summary of CPU, motherboard, RAM, graphics, and storage.

Download utilities only from their official sites. Avoid unofficial mirrors and bundled installers, and do not assume a program’s upgrade recommendation is authoritative. Verify compatibility with the computer or motherboard manufacturer.

Quick reference

For a compact record, save the computer model, operating-system version and architecture, CPU, core and thread count, installed and usable RAM, RAM speed and type, GPU and memory, primary storage and free space, motherboard, BIOS/UEFI, network adapter, and display resolution.
