Open Command Prompt and type wmic bios get smbiosbiosversion or wmic bios get biosversion to display the BIOS/UEFI version. 2. Use the System Information tool by typing msinfo32 in the Run dialog, then check the BIOS Version/Date entry for complete details including manufacturer and release date. 3. In PowerShell, run Get-WmiObject win32_bios | Select-Object SMBIOSBIOSVersion or Get-CimInstance -ClassName Win32_BIOS to retrieve BIOS version and additional firmware information. 4. Observe the BIOS version during boot by watching the POST screen or entering BIOS setup using keys like F2, Del, F10, or Esc. 5. Optionally, use third-party tools like CPU-Z, Speccy, or HWiNFO, and check the Mainboard tab for BIOS version and date. Always verify the exact model-specific version before updating and distinguish BIOS version from Windows version, ensuring accurate firmware identification through any of these methods.
Checking your BIOS version in Windows is a straightforward process, and there are several methods you can use—depending on whether you prefer the command line, graphical tools, or third-party software. Here are the most reliable ways:

1. Using Command Prompt (Recommended)
This is the quickest and most common method.
-
Press
Win R
to open the Run dialog. Type
cmd
and press Enter.-
In the Command Prompt window, type the following command and press Enter:
wmic bios get smbiosbiosversion
Or, for more detail:
wmic bios get biosversion
You might see one or more version numbers listed—this is your BIOS or UEFI firmware version.
Note: On some systems, especially newer ones with UEFI, the output might show multiple entries or slightly different naming, but it will still reflect the firmware version.
2. Using System Information Tool
This method uses a built-in Windows GUI tool.
- Press
Win R
, typemsinfo32
, and press Enter. - Wait for the System Information window to load.
- Look for the BIOS Version/Date entry.
- It will show something like:
American Megatrends Inc. 2.10, 6/15/2022
- It will show something like:
This gives you not only the version but also the manufacturer and release date, which helps determine if an update might be available.
3. Using PowerShell
PowerShell offers another quick way:
Press
Win X
and select Windows PowerShell or Terminal.Run this command:
Get-WmiObject win32_bios | Select-Object SMBIOSBIOSVersion
Or for more details:
Get-CimInstance -ClassName Win32_BIOS
This will display the BIOS version, release date, and other related info.
4. Check During Boot (Before Windows Loads)
If Windows isn’t booting or you want to verify independently:
- Restart your computer.
- Watch the screen closely as it starts up.
- The BIOS version is often displayed in the corner (e.g., bottom right) during the POST (power-on self-test).
- You may need to pause the boot by pressing a key like Pause/Break to read it.
Alternatively, enter the BIOS setup (usually by pressing F2, Del, F10, or Esc during startup) — the version is typically shown on the main screen.
5. Using Third-Party Tools (Optional)
Tools like CPU-Z, Speccy, or HWiNFO can also report BIOS version with additional system insights. These are helpful if you're already diagnosing hardware.
- Download and run CPU-Z.
- Go to the Mainboard tab.
- Look for "BIOS" — it will show the version and date.
Quick Tips:
- BIOS versions are often specific to your exact model and motherboard.
- Always double-check the version before attempting a BIOS update.
- Don’t confuse BIOS version with Windows version.
Basically, just open Command Prompt or System Information, run one command or glance at the BIOS line, and you’ll know exactly what firmware your system is running.
