Find your specs in Windows using System Information

The fastest way to see what's inside your computer is to open the built-in System Information tool. Press the Windows key and the letter R at the same time, type msinfo32 into the box that appears, and press Enter. A window will open showing your processor, RAM, system type, and Windows version all in one place.

Look for these key details: the Processor line tells you what CPU you have and its speed in GHz. The Installed RAM line shows your memory in gigabytes. The System Type line tells you whether you're running 32-bit or 64-bit Windows. If you need to know your graphics card, scroll down to the "Components" section on the left, click "Display", and you'll see your video card listed under "Adapter Description".

This tool shows you almost everything a technician would need to troubleshoot problems or recommend software. Write down or screenshot what you see — you may need it later if you contact support or want to upgrade a part.

Check your specs on a Mac using About This Mac

On a Mac, click the Apple menu in the top-left corner and select About This Mac. A window opens when ready showing your processor, memory, graphics card, and macOS version. This is the Mac equivalent of Windows System Information and contains the same essential details.

The Processor line shows your CPU and core count. The Memory line shows your RAM. The Graphics line shows your video card. If you need storage information, click the Storage tab to see how much space your drive has and how much is currently in use.

Macs also let you check specs through System Settings. Click the Apple menu, select System Settings, then click General on the left and About. You'll see the same core information in a different layout.

Key Takeaways

  • On Windows, press Windows key + R, type msinfo32, and press Enter to see processor, RAM, system type, and graphics card in one window.
  • On a Mac, click the Apple menu and select About This Mac to view the same information when ready.
  • Your processor speed (measured in GHz), RAM amount (in gigabytes), and system type (32-bit or 64-bit) are the three specs most programs and support staff will ask about.
  • Write down or screenshot your specs before contacting support or shopping for software upgrades, since you may need them during the conversation.
  • Graphics card information is usually found in a separate section — under "Display" in Windows System Information or in the main window on a Mac.

Find storage and drive information

Your hard drive or solid-state drive (SSD) capacity and how much space is left are separate from the specs shown in System Information. On Windows, open File Explorer, right-click This PC on the left side, and select Properties. You'll see each drive listed with its total size and how much space is used.

On a Mac, click the Apple menu, select About This Mac, then click the Storage tab. You'll see a bar showing your total drive capacity and a breakdown of what's using the space — applications, documents, photos, and system files.

If you're running low on storage, this view helps you understand what's taking up room. Most computers slow down noticeably when the drive is more than 85 percent full, so knowing your storage situation matters for performance.

Check your network and device information

If you need to know your IP address, MAC address, or network adapter details, Windows users can open Command Prompt (search for "cmd" in the Windows search box) and type ipconfig /all, then press Enter. This shows your IP address, MAC address, and network adapter name.

Mac users can click the Apple menu, select System Settings, click General, then About. Scroll down to find your IP address listed under "Wi-Fi Address" or "Ethernet Address" depending on how you're connected. For your MAC address, click System Settings, then Network, select your connection type, and click Details.

You'll need this information if you're setting up a printer on your network, troubleshooting internet problems, or configuring a router. Most people don't need these details for everyday use, but they're useful to have when something isn't working.

Understand what each specification means

Your processor (CPU) is the brain of your computer. A faster processor (higher GHz number) handles tasks more quickly. Common processors are Intel Core i3, i5, i7, or AMD Ryzen 3, 5, 7. The higher the number, the more powerful it is, but a newer i5 often outperforms an older i7.

RAM (memory) is how much work your computer can do at once. 8 gigabytes is the minimum for comfortable use today. 16 gigabytes handles heavy multitasking, video editing, or gaming. 32 gigabytes or more is for professional work like 3D rendering or running virtual machines. If you have less than 8 GB, your computer will feel slow when you open multiple programs.

Your graphics card (GPU) handles images and video. Integrated graphics (built into your processor) work fine for web browsing, email, and office work. Dedicated graphics cards (NVIDIA or AMD) are needed for gaming, video editing, or 3D work. Your specs will show which type you have.

Storage is how much you can save on your computer. An SSD (solid-state drive) is much faster than an older hard drive (HDD). Most new computers come with SSDs. Your storage doesn't affect speed the way RAM does, but a full drive will slow your computer down.

Export or save your specs for later

If you need to keep a record of your computer's specifications, Windows System Information lets you save the information as a text file. Open System Information (Windows key + R, type msinfo32), click File at the top, then Export. Choose where to save the file and give it a name. You'll get a text file with all your specs that you can open anytime or email to a technician.

On a Mac, you can take a screenshot of the About This Mac window by pressing Command + Shift + 4, then dragging to select the window. The screenshot saves to your desktop. You can also open Notes, take a screenshot, and paste it there for safekeeping.

Keeping a record is especially useful if you're troubleshooting a problem with support staff, shopping for software that has system requirements, or planning an upgrade. A saved file or screenshot means you won't have to look up the information twice.

Frequently Asked Questions

What should I do if I don't understand what one of my specs means?

Write down the exact name and number you see, then search for it online. For example, if you see "Intel Core i7-12700K", search that exact model number and you'll find comparisons and reviews that explain what it can do. Most specs are easier to understand when you see them compared side by side with other models.

Can I check my specs on a Chromebook?

Chromebooks show fewer specs than Windows or Mac computers because they're designed to be simpler. Click the time in the bottom-right corner, click the settings gear, then scroll down and click About Chrome OS. You'll see your processor, RAM, and storage, but not as much detail as other systems.

Why does my computer show less RAM than I thought I had?

Your operating system reserves some RAM for itself, so the amount shown in System Information may be slightly less than what you bought. If you bought 16 GB but see 15.9 GB, that's normal. If the difference is much larger, one of your RAM sticks may have failed or not be seated properly.

Is my computer too old if my specs are low?

Not necessarily. A computer with an older processor but a solid SSD and 16 GB of RAM will feel faster than a newer computer with less RAM and a slow hard drive. Check what you actually use your computer for — if you browse the web and use email, even older specs work fine. If you want to edit video or play new games, you'll need more power.

Where do I find my Windows or macOS version number?

On Windows, open System Information (Windows key + R, type msinfo32) and look for "OS Name" — it will say something like "Windows 11" or "Windows 10". On a Mac, click the Apple menu, select About This Mac, and look at the top line, which will say something like "macOS Sonoma" or "macOS Ventura".
