How to check your BIOS version in Windows 11

The fastest way to check your BIOS version is to open the System Information app. Press the Windows key and R together, type msinfo32, and press Enter. Look for the line labeled "BIOS Version/Date" — this shows both your BIOS version number and when it was released. Close the window when you're done.

If that method doesn't work or you prefer a different route, Windows 11 offers several other ways to find this information. Each method takes less than a minute and requires no special tools or downloads. The information you find will be the same regardless of which method you choose.

Key Takeaways

  • System Information (msinfo32) is the quickest method and shows your BIOS version and release date in one window.
  • Settings > System > About also displays BIOS version under "System firmware" and works on all Windows 11 machines.
  • Command Prompt and PowerShell can retrieve BIOS information if you prefer typing commands over clicking menus.
  • Your BIOS version number helps you determine whether updates are available for your motherboard or laptop.
  • BIOS version numbers vary by manufacturer and may appear as dates, letters, or numbered sequences depending on your hardware maker.

Using the Settings app to find BIOS version

Open Settings by pressing the Windows key and I together. Navigate to System in the left sidebar, then click About. Scroll down until you see "System firmware" — the version number listed there is your BIOS version. This method works on every Windows 11 machine and doesn't require opening additional programs.

The Settings method is useful if you're already in Settings for another reason or if you want to see your BIOS version alongside other system details like your device name and Windows version. The information appears in the same format as System Information, so both methods show the same data. Many users find this approach more intuitive because it uses the familiar Settings interface.

Checking BIOS version from Command Prompt

Open Command Prompt by pressing the Windows key, typing cmd, and pressing Enter. Type the following command and press Enter:

wmic bios get smbiosbiosversion

The result shows your BIOS version number. This method works on any Windows 11 system with Command Prompt access and doesn't require navigating menus. Some users prefer this approach because it displays only the information you asked for, without extra details cluttering the screen.

Using PowerShell to retrieve BIOS information

Right-click the Windows Start button and select Terminal (Admin), or search for PowerShell in the Start menu. In the window that opens, type the following command and press Enter:

Get-WmiObject win32_bios | Format-List SMBIOSBIOSVersion

PowerShell displays your BIOS version on the next line. This method is similar to Command Prompt but uses PowerShell's object-based approach. Both Command Prompt and PowerShell retrieve the same information from your system, so choose whichever you're more comfortable using. PowerShell is built into Windows 11 and requires no additional installation.

Why you might need to know your BIOS version

Knowing your BIOS version helps you determine whether your motherboard or laptop has the latest firmware. Manufacturers release BIOS updates to fix bugs, improve hardware compatibility, add security patches, or enable support for newer processors. Before updating, you need to know what version you currently have so you can check whether a newer one exists on your manufacturer's support page.

Your BIOS version also matters when troubleshooting hardware problems. Tech support or online forums may ask for your BIOS version to help diagnose issues or recommend specific fixes. Having this number ready saves time during the troubleshooting process and helps others understand your exact system configuration.

Understanding BIOS version numbers

BIOS version numbers vary by manufacturer and don't follow a single standard format. Some show dates (like 12/15/2023), while others use version numbers (like F14 or 1.2.3). The exact format depends on whether your computer is a laptop from a manufacturer like Dell or Lenovo, or a desktop with a motherboard from ASUS, MSI, or Gigabyte.

The important thing is that your version number lets you compare against what's available on your manufacturer's website. Once you have your version, visit the support page for your specific model and look for BIOS downloads — the site will show you whether a newer version exists and what changes it includes. Keeping track of your current version makes it easy to spot when updates become available.

Frequently Asked Questions

What's the difference between BIOS and UEFI?

UEFI is the modern replacement for BIOS and handles the same job — starting your computer and managing hardware before Windows loads. Windows 11 requires UEFI, so if you're running Windows 11, you have UEFI, not traditional BIOS. The terms are often used interchangeably now, and the methods above work for both.

Can I update my BIOS from Windows 11?

Most BIOS updates require restarting your computer and running the update from a special boot screen, not from Windows itself. Some manufacturers offer Windows-based update tools that handle the restart automatically, but you'll need to check your specific motherboard or laptop manufacturer's website to see what method they support.

Is it safe to update my BIOS?

BIOS updates are generally safe when done correctly, but they carry more risk than regular software updates because a failed BIOS update can make your computer unbootable. Only update if your manufacturer recommends it for a specific reason — security fix, hardware support, or a problem you're experiencing — and follow their instructions exactly.

Why does my BIOS version show a date instead of a number?

Some manufacturers, particularly laptop makers, use release dates as version numbers. A BIOS version showing "12/15/2023" means it was released on December 15, 2023. This format is just as valid as numbered versions — it's simply a different way of identifying which release you have.

Where do I find BIOS updates for my computer?

Visit your computer manufacturer's support website and search for your specific model number. Look for a downloads or drivers section, then find BIOS or firmware updates. The page will list available versions and explain what each update fixes or improves, so you can decide whether updating is necessary for your situation.
