How to Check PC Specs on Windows 11: Processor, RAM, Graphics and Storage

Here is how to check PC specs on Windows 11 without installing any extra software. Windows shows your processor, memory, graphics card, storage and Windows version in several built-in places, and each one adds a little more detail. The fastest is Settings > System > About; the most complete is System Information (msinfo32). This guide walks through each tool, explains what the numbers mean, and covers the common reasons you might need them, such as checking a game’s requirements or selling a computer.

Which tool shows what

What you want to know	Quickest place to look
Processor (CPU)	Settings > System > About, or Task Manager > Performance > CPU
Amount of RAM	Settings > System > About
RAM speed and slots used	Task Manager > Performance > Memory
Graphics card (GPU)	Task Manager > Performance > GPU, dxdiag, or Device Manager
Storage size and free space	Settings > System > Storage, or File Explorer > This PC
SSD or hard drive	Task Manager > Performance > Disk
PC maker and model	System Information (msinfo32)
Windows edition and version	Settings > System > About, or winver
BIOS mode and Secure Boot	System Information (msinfo32)

1. Settings > System > About (the quick overview)

1. Press Windows + I to open Settings.
2. Select System, then scroll down and select About. The shortcut Windows + Pause/Break opens the same page, if your keyboard has that key.

Under Device specifications you will see:

• Device name: the name the PC uses on your network.
• Processor: the CPU model and its base speed in GHz.
• Installed RAM: total memory, sometimes with a smaller “usable” figure next to it, because part of the memory may be reserved, for example for built-in graphics.
• System type: should say 64-bit operating system, x64-based processor (or ARM-based on some newer laptops).

Under Windows specifications you will see the Edition (Home or Pro, for example), the Version and the OS build. There is a Copy button next to each section, which is handy if you want to paste the details into an email or a listing.

2. Task Manager: live details on CPU, memory, disk and GPU

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Select Performance in the left-hand menu (the icon that looks like a heart-rate graph). If you only see a small window, click More details first.
3. Click each item:
   • CPU: the processor name at the top right, plus base speed, number of cores and logical processors, and whether virtualization is enabled.
   • Memory: total RAM, speed, how many of the memory slots are used, and the form factor (such as SODIMM in many laptops). This is useful if you are thinking about adding RAM.
   • Disk 0, Disk 1…: the drive model, and its type (SSD or HDD).
   • GPU: the graphics card name, dedicated GPU memory if it has its own, and driver version. Some PCs show two GPUs, for example built-in Intel or AMD graphics plus a separate NVIDIA or AMD card.

Task Manager also shows how busy each part is right now, which helps if your computer is slow. Our guide to speeding up a slow laptop explains what to do with that information.

3. System Information (msinfo32): the full summary

1. Press Windows + R, type msinfo32 and press Enter. You can also search for System Information in the Start menu.
2. The System Summary page lists the OS name and version, System Manufacturer, System Model, Processor, BIOS Version/Date, BIOS Mode (UEFI or Legacy), Secure Boot State and Installed Physical Memory (RAM).
3. Expand Components > Display for graphics details, or Components > Storage > Disks for drive sizes.

To save everything as a text file, choose File > Export. That is useful when someone helping you needs the full picture.

BIOS Mode and Secure Boot State matter for Windows 11 compatibility. If you are checking whether an older PC can run Windows 11, see our guide on a PC that doesn’t meet Windows 11 requirements (TPM and Secure Boot).

4. DirectX Diagnostic Tool (dxdiag): graphics card details

1. Press Windows + R, type dxdiag and press Enter. If asked whether to check whether drivers are digitally signed, you can choose Yes.
2. The System tab shows the processor, memory and DirectX version.
3. The Display tab (there may be more than one) shows the graphics card Name, Manufacturer, its memory, and the driver version and date.

Game publishers often ask for dxdiag information when you report a problem. Click Save All Information to create a text file you can attach.

5. Device Manager: confirm the graphics card and other hardware

Right-click the Start button and choose Device Manager. Expand Display adapters to see your graphics card, Processors to see the processor (listed once per logical processor), and Disk drives to see your drives. A yellow warning sign next to a device means a driver problem; our guide to updating device drivers safely explains how to fix it.

6. Storage: how much space you have

Go to Settings > System > Storage to see used and free space and what is using it. For individual drives and partitions, open Advanced storage settings > Disks & volumes. You can also open File Explorer and select This PC to see each drive and its free space at a glance. If space is tight, see our guide to freeing up disk space.

7. winver: the exact Windows version

Press Windows + R, type winver and press Enter. A small window shows the Windows version (such as 24H2) and the OS build number. Software makers and support pages sometimes ask for this. Microsoft’s release information page lists which versions are still supported.

Windows 10 reached end of support on 14 October 2025, so if winver shows Windows 10, it no longer receives security updates. On Windows 10, the About page is at Settings > System > About as well.

Why your PC specs matter

• Software and game requirements. Programs and games list minimum and recommended specs. Compare the processor, RAM, graphics card and free storage with your own before buying. “Minimum” usually means it will run, not that it will run well.
• Upgrading. Task Manager’s memory slot count and the storage type tell you whether adding RAM or switching to an SSD is an option. The PC maker’s support site, searched by model number, lists what your model supports.
• Windows 11 compatibility. The processor, TPM, Secure Boot and BIOS mode all count. See the Windows 11 requirements guide.
• Selling or giving away a PC. Buyers ask for the processor, RAM, storage size and type, graphics card and Windows edition. Collect them before you reset Windows and wipe your files. A screenshot of the About page is a quick way to share them; our guide on how to take a screenshot on Windows 11 shows how.
• Getting help. Whether you contact the PC maker or a local repair shop, having the model and specs ready saves time.

A word about “free PC scan” sites

You do not need to download a “system scanner” or give anyone remote access to find your specs. Pop-ups or callers claiming your PC “needs a scan” are a common scam. Everything above is built into Windows. For more Windows guides, visit the Windows topic hub.
