The fastest way to see your PC specs
Open the Settings app by pressing the Windows key and typing "settings", then select the Settings icon. Go to System in the left menu, then click About. This page shows your processor, RAM, system type, and Windows version in about 10 seconds — no downloads or restarts needed.
If you need more detail than the About page provides, Windows 10 has three other built-in tools that each show different information. The method you choose depends on what specs you're looking for and how technical you want to get.
Key Takeaways
- The Settings app's About page is the quickest way to see processor, RAM, and Windows version without opening any other programs.
- System Information shows more detail, including motherboard model, BIOS version, and device drivers, and opens from the same Settings menu.
- Device Manager lists every hardware component installed in your PC, including graphics card, sound card, and network adapter.
- DirectX Diagnostic Tool is the best choice for checking graphics card memory, audio device details, and display settings all in one window.
Using the Settings About page for basic specs
Press the Windows key on your keyboard and type "settings" without quotes. Click the Settings app icon (it looks like a gear). On the left side, click System, then scroll down and click About.
The About page displays your Device name (the name you gave your PC), Processor (CPU model and speed), Installed RAM (memory in gigabytes), System type (32-bit or 64-bit), and Windows specifications (edition and build number). This is enough information for most people who just need to know what they're working with.
Opening System Information for detailed hardware information
From the Settings About page, click the link that says System information near the top. This opens a larger window with two columns. The left side lists categories; the right side shows the details for each one.
System Information includes everything on the About page plus your System Manufacturer and System Model (useful if you bought a pre-built PC and need to find drivers), BIOS Version/Date, System Boot Time, and Installed Physical Memory broken down by slot. Scroll down in the right column to see more entries. This tool is most useful when you're troubleshooting or need to match hardware to a driver read.
Finding graphics card and audio specs with DirectX Diagnostic Tool
Press the Windows key and type "dxdiag" without quotes, then press Enter. The DirectX Diagnostic Tool opens. Click the Display tab to see your graphics card name, memory (VRAM), driver version, and current display resolution.
Click the Audio tab to see your sound card model and driver details. The System tab repeats your processor and RAM but also shows your system language and the date DirectX was last updated. This tool is faster than System Information if you only need graphics or audio specs, and it's the standard way to check VRAM on a graphics card.
Using Device Manager to see all installed hardware
Press the Windows key and type "device manager" without quotes, then press Enter. Device Manager opens as a tree list. Each category (like Display adapters, Sound, video and game controllers, Network adapters) can be expanded by clicking the arrow next to it.
Click the arrow next to Processors to see how many CPU cores your system has listed. Expand Disk drives to see your hard drive or SSD model and size. This view is useful when you want to see every single piece of hardware Windows recognizes, or when you need to check if a device is working properly (a yellow warning triangle means a driver problem).
Checking Windows 10 edition and build number
Your Windows 10 edition (Home, Pro, Enterprise) and build number both appear on the Settings About page. The Edition tells you which version of Windows 10 you own. The OS Build is a longer number like "19045.3693" that tells you which update version you're running.
If you need to know whether your Windows 10 is fully updated, compare your OS Build number to Microsoft's latest release notes online. A higher build number means you have a newer update installed. You can also press Windows key + R, type "winver" without quotes, and press Enter to see the same information in a smaller popup window.
What to do if a spec doesn't display or shows as unknown
If a hardware component shows as "Unknown device" in Device Manager, Windows doesn't have a driver for it. Right-click the unknown device, select Update driver, then choose Search automatically for updated driver software. Windows will search online and install the correct driver if it finds one.
If a spec is blank or missing from System Information, restart your PC and check again. Sometimes hardware information doesn't load until after a restart. If it's still missing after a restart, the hardware may not be properly connected inside your PC, or the driver may be corrupted. In that case, opening Device Manager and looking for yellow warning triangles will usually point to the problem.
Frequently Asked Questions
How do I find out how much storage space my hard drive has?
Open File Explorer (the folder icon on your taskbar), right-click This PC in the left menu, and select Properties. You'll see the total capacity and used space for each drive. Device Manager shows the drive model but not the capacity; the About page doesn't show storage at all.
Where do I find my graphics card memory (VRAM)?
Open DirectX Diagnostic Tool (press Windows key, type "dxdiag", press Enter), then click the Display tab. The Dedicated Video Memory line shows your graphics card's VRAM in megabytes or gigabytes. This is the most reliable place to check VRAM on Windows 10.
Can I see my PC specs without opening Settings?
Yes. Right-click the This PC icon on your desktop or in File Explorer, then select Properties. This opens a window showing processor, RAM, and system type. It's slightly faster than opening Settings, though it shows less information overall.
What does "System type 64-bit" mean?
A 64-bit system can use more than 4 gigabytes of RAM and runs 64-bit software. A 32-bit system is limited to about 3.5 GB of RAM. Almost all modern PCs are 64-bit. This matters when you're downloading software — some programs come in 32-bit and 64-bit versions, and you should match your system type.
How do I know if my PC is running the latest Windows 10 update?
Go to Settings > System > About and look at the OS Build number. Visit Microsoft's Windows 10 release information page online and compare your build number to the latest one listed. If your number is lower, you can go to Settings > Update & Security > Windows Update and click Check for updates to install the newest version.
