How to Check Your PC Specs on Windows 11

Why Check Your Specs

You need your specs to know whether a game will run, whether you can add RAM or an SSD, or to give a technician the right details in a support ticket. Windows 11 shows all of it without third-party tools—the information is just scattered across four different places.

Step 1: Settings — CPU, RAM, Windows Edition

  1. Open Settings (Win + I) → System → About.
  2. Device specifications lists your processor, installed RAM, system type (64-bit), and Device ID.
  3. Windows specifications lists your edition, version (e.g. 24H2), and OS build.

The version and build numbers are the two most useful things to quote when asking for help, because a fix that works on one build often does not exist on another.

Step 2: Task Manager — Live Detail and GPU

  1. Press Ctrl + Shift + Esc → Performance tab.
  2. CPU — model, base speed, Cores, Logical processors, and the Virtualization line (needed for WSL, Hyper-V, and Android emulators).
  3. Memory — total capacity, Speed in MT/s, Slots used (e.g. 2 of 4), and Form factor (DIMM for desktops, SODIMM for laptops). This tells you instantly whether a RAM upgrade means adding a stick or replacing what is there.
  4. GPU — the graphics card name and Dedicated GPU memory. Laptops show two entries when they have both integrated and discrete graphics.
  5. Disk — the drive model and, at the top right, whether it is SSD or HDD.

Step 3: System Information — Motherboard and BIOS

  1. Press Win + R, type msinfo32, press Enter.
  2. In System Summary, read:
    • System Manufacturer / System Model — the laptop or prebuilt model, which is what you type into a support site.
    • BaseBoard Manufacturer / BaseBoard Product — the motherboard, which you need for chipset drivers.
    • BIOS Version/Date and BIOS Mode (UEFI or Legacy).
    • Secure Boot State — relevant for Windows 11 upgrades and some anti-cheat systems.
    • Installed Physical Memory and Total Physical Memory.
  3. Expand Components → Display for full GPU detail, or Storage → Drives for disk sizes and free space.

You can save a full report from File → Export, which is a good thing to attach to a support email.

Step 4: DirectX Diagnostic Tool — Gaming Specs

  1. Press Win + R, type dxdiag, press Enter.
  2. The System tab summarises CPU, RAM, and DirectX version.
  3. The Display tab shows the GPU, its memory, the driver version, and the driver date—the exact three things a game's support team will ask for.
  4. Click Save All Information to produce a text file you can attach to a ticket.

Step 5: Command Line, If You Prefer It

Open Terminal and use PowerShell:

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

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

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

Get-PhysicalDisk | Select-Object FriendlyName, MediaType, Size

The memory query is the useful one before a RAM purchase: it gives you the exact part number and speed of the modules already fitted, so you can buy something that matches.

Quick Reference: Where Each Spec Lives

  • CPU and RAM amount — Settings → About, or Task Manager → Performance.
  • RAM speed and free slots — Task Manager → Performance → Memory.
  • GPU and driver version — Task Manager → Performance → GPU, or dxdiag → Display.
  • Motherboard, BIOS, Secure Boot — msinfo32 → System Summary.
  • Drive type (SSD vs HDD) — Task Manager → Performance → Disk.
  • Serial number / service tag — wmic bios get serialnumber in Command Prompt, or the sticker underneath a laptop.

Reading the Numbers Before an Upgrade

  • RAM: 8 GB is the practical floor for Windows 11; 16 GB is comfortable. If Task Manager shows 1 of 2 slots used, adding a matching stick is the cheapest meaningful upgrade—see how to check and upgrade RAM and how much RAM do I need.
  • Storage: if Disk says HDD, that is your bottleneck, not the CPU. See how to choose an SSD.
  • GPU: compare the exact model to a game's requirements, not the amount of VRAM. 8 GB on a slow card is still a slow card.
