Knowing your computer’s BIOS version is important when troubleshooting hardware problems, updating firmware, checking compatibility with new processors or memory, or following your motherboard manufacturer’s support instructions. The BIOS (Basic Input/Output System), or UEFI firmware on modern computers, initializes your hardware before Windows starts and plays a critical role in system stability and performance. Manufacturers regularly release BIOS updates that may fix bugs, improve hardware compatibility, enhance security, and add support for newer components.
Before installing a BIOS update, it’s essential to verify the version currently installed on your computer. Comparing your existing BIOS version with the latest release available from your computer or motherboard manufacturer helps determine whether an update is necessary. Fortunately, Windows provides several easy ways to check the BIOS version without opening your computer or entering the BIOS setup screen.
This guide explains multiple methods to check your BIOS version in Windows 11 and Windows 10, including using System Information, Command Prompt, PowerShell, the Registry Editor, and the BIOS setup utility.
Why Check Your BIOS Version?
Checking your BIOS version helps you determine whether your computer is running the latest firmware.
It’s also useful when troubleshooting hardware compatibility issues, verifying update requirements, contacting technical support, or confirming that a BIOS update installed successfully.
Many motherboard manufacturers request the BIOS version when diagnosing startup problems or recommending firmware updates.
Method 1: Check BIOS Version Using System Information
System Information is the easiest and most commonly used method.
Press Windows + R to open the Run dialog.
Type msinfo32.
Press Enter.
The System Information window opens.
In the System Summary section, locate the following entry:
BIOS Version/Date
This field displays:
- BIOS manufacturer
- BIOS version
- Release date
You can also view additional details such as:
- BaseBoard Manufacturer
- BaseBoard Product
- BIOS Mode (UEFI or Legacy)
- Secure Boot State
This method works on both Windows 11 and Windows 10.
Method 2: Check BIOS Version Using Command Prompt
Command Prompt can display your BIOS version with a simple command.
Open Command Prompt.
Type the following command:
wmic bios get smbiosbiosversionPress Enter.
Windows displays the installed BIOS version.
To view additional BIOS details, use:
wmic bios get manufacturer, smbiosbiosversion, releasedateThis displays:
- BIOS manufacturer
- BIOS version
- Release date
Although the WMIC tool is deprecated on newer Windows versions, it remains available on many systems.
Method 3: Check BIOS Version Using PowerShell
PowerShell also provides BIOS information.
Open PowerShell.
Enter the following command:
Get-CimInstance Win32_BIOSPress Enter.
PowerShell displays information including:
- Manufacturer
- BIOS version
- Release date
- Serial number
- SMBIOS version
This method works well on modern Windows installations and is recommended when WMIC isn’t available.
Method 4: Check BIOS Version from the BIOS Setup Screen
You can also view the BIOS version directly within the firmware interface.
Restart your computer.
Press the appropriate BIOS key during startup.
Common keys include:
- Delete
- F2
- F10
- Esc
- F12 (on some systems)
After entering the BIOS or UEFI setup, locate the system information page.
The BIOS version usually appears near the top of the main screen.
Some manufacturers also display:
- BIOS build date
- Motherboard model
- CPU information
- Installed memory
Exit the BIOS without saving changes if you don’t intend to modify any settings.
Method 5: Check BIOS Version Using Registry Editor
Windows stores BIOS information in the system registry.
Press Windows + R.
Type regedit.
Press Enter.
Navigate to:
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\BIOSLook for values such as:
- BIOSVendor
- BIOSVersion
- BIOSReleaseDate
These entries display your current BIOS information.
Avoid modifying registry values unless you understand their purpose.
Method 6: Check BIOS Version Using DirectX Diagnostic Tool
Although primarily intended for hardware diagnostics, the DirectX Diagnostic Tool also displays firmware information.
Press Windows + R.
Type:
dxdiagPress Enter.
Allow DirectX Diagnostic Tool to load.
Review the System tab.
Depending on your computer manufacturer, BIOS information may be listed alongside other system specifications.
How to Compare BIOS Versions
After identifying your BIOS version, compare it with the latest version available on your computer or motherboard manufacturer’s support website.
Download a newer BIOS only if:
- It fixes a problem you’re experiencing.
- It improves hardware compatibility.
- It adds support for new processors or memory.
- The manufacturer specifically recommends updating.
Avoid installing BIOS updates simply because a newer version exists.
BIOS Version vs BIOS Date
Many users confuse the BIOS version with the BIOS release date.
The version identifies the firmware revision installed on your motherboard.
The release date indicates when that firmware version was published.
Both pieces of information are useful when determining whether an update is required.
What If the BIOS Version Looks Different?
Some manufacturers use unique version numbering systems.
For example, one manufacturer may use version numbers like F12, while another may use 3205, 1.28, or A15.
Always compare the version format used by your specific manufacturer instead of assuming higher-looking numbers from another brand indicate newer firmware.
Common Problems When Checking BIOS Version
Occasionally Windows may display incomplete BIOS information.
Restarting the computer often refreshes the firmware details.
If System Information doesn’t display the BIOS version correctly, try using PowerShell or entering the BIOS setup directly.
Older systems may report legacy BIOS information instead of UEFI details.
This is normal for older hardware.
Tips Before Updating Your BIOS
Always identify your exact motherboard or computer model before downloading firmware.
Download BIOS updates only from the official support website for your computer or motherboard manufacturer.
Read the release notes to understand what changes the update includes.
If your system is stable and the update doesn’t address a problem that affects you, updating the BIOS may not be necessary.
Why Knowing Your BIOS Version Matters
The BIOS version helps determine hardware compatibility and whether firmware updates are available.
It also simplifies technical support by allowing manufacturers to identify your firmware quickly.
When upgrading processors, installing faster memory, or troubleshooting startup issues, knowing your BIOS version can save time and prevent compatibility problems.
Keeping track of your firmware version also helps verify that BIOS updates have been installed successfully.
Conclusion
Checking your BIOS version is a simple but important step when maintaining your Windows computer. Whether you’re planning to update your firmware, troubleshoot hardware issues, verify compatibility with new components, or follow your manufacturer’s support recommendations, knowing the installed BIOS version helps you make informed decisions. Windows provides several convenient ways to view this information, including System Information, Command Prompt, PowerShell, Registry Editor, and the BIOS setup utility itself, allowing both beginners and advanced users to access firmware details quickly.
Before updating your BIOS, always compare your current version with the latest release available from your computer or motherboard manufacturer. Only install updates that address issues affecting your system or provide support for hardware you plan to use. By regularly checking your BIOS version and keeping accurate firmware information, you can improve troubleshooting, maintain system stability, and ensure your computer remains compatible with the latest hardware and software updates.
