How to Check Your PC Specs in Windows 10

To check your PC specs in Windows 10, select Start > Settings > System > About. Under Device specifications, you’ll see the processor, installed RAM, and whether Windows is 64-bit. For every detail, including the motherboard and BIOS, open System Information.

Applies to: Windows 10. Microsoft ended Windows 10 support on October 14, 2025, so a PC without Extended Security Updates no longer receives security fixes; that program runs until October 12, 2027.

Quick check in Settings

Select Start > Settings > System > About. It shows:

• Processor (CPU)
• Installed RAM
• System type (64-bit or 32-bit)
• Edition and Version of Windows, under Windows specifications

Full details in System Information

1. Press Windows logo key + R, type msinfo32, and press Enter.
2. System Summary lists the processor, BIOS version, motherboard, and installed memory. The processor name also tells you which processor generation you have.
3. Expand Components > Display for your graphics card, or Storage > Disks for your drives.

Check the graphics card, CPU, and memory in Task Manager

1. Press Ctrl + Shift + Esc to open Task Manager, and select More details if needed.
2. Select the Performance tab.
3. Select CPU, Memory, Disk, or GPU to see the model, size, and speed.

Each page shows more than the name:

• CPU: the number of cores and logical processors, and the base speed.
• Memory: total RAM, its speed, and Slots used, such as 2 of 4. Free slots mean you can add more RAM.
• Disk: the drive model and whether it’s an SSD or HDD.
• GPU: the dedicated video memory and, on many graphics cards, the GPU temperature.

Other ways

• Command Prompt: type systeminfo and press Enter for a full text summary.
• DirectX Diagnostic Tool: press Windows logo key + R, type dxdiag, and press Enter. The Display tab shows the graphics card.
• Storage: select Settings > System > Storage to see how much space is used and free. Want the drive’s full capacity and whether it’s an SSD or HDD? Task Manager shows both, as explained in how to check SSD size in Windows 10.
• PowerShell: run Get-ComputerInfo for a long list of Windows and hardware details. To see only part of it, add a property filter, for example Get-ComputerInfo -Property “Bios*”.

Find your PC’s exact model and serial number

You often need these for drivers, warranty checks or support calls. Open PowerShell and run:

• Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model for the maker and model
• Get-CimInstance Win32_BIOS | Select-Object SerialNumber for the serial number

On many laptops, the same details are also printed on a sticker underneath or inside the battery bay.

Save your specs to share

• In System Information, select File > Export to save every detail as a text file.
• In Command Prompt, run systeminfo > %userprofile%\Desktop\specs.txt to put a summary on your desktop.
• In the DirectX Diagnostic Tool, select Save All Information. This report is useful for game support.

Troubleshooting

• Installed RAM shows something like “16.0 GB (15.8 GB usable)”. That’s normal. Integrated graphics and hardware reserve a little memory.
• The graphics card doesn’t appear in Task Manager. Its driver may be missing. Check Device Manager under Display adapters and install the driver from the maker.
• systeminfo takes a while. It gathers update and network details too. Wait a minute for it to finish.

Frequently asked questions

Can I check my PC’s temperature?

Task Manager shows the GPU temperature on the GPU page for many dedicated graphics cards. Windows 10 doesn’t show CPU temperature. Check it in your PC’s BIOS or UEFI setup screen, or in your PC or motherboard maker’s utility.

How do I check how much RAM I have?

See Installed RAM on the About page. Speed, slots, and type are covered in checking RAM in Windows 10.

Can my PC run Windows 11?

Compare your specs with Windows 11’s requirements, or use Microsoft’s PC Health Check app. If it passes, you can upgrade Windows 10 to 11.

How do I check my specs if Windows won’t start?

Look for the model sticker on the PC, then search the model on the maker’s website. Many PCs also show the processor and memory in their BIOS or UEFI setup screen.

Which specs matter most for speed?

For everyday use, an SSD and at least 8 GB of RAM make the biggest difference. For games, the graphics card matters most.
