Key Takeaway:

  • To check your BIOS version graphically, open the Start menu, find System Information, choose System Summary in the left sidebar, and look for BIOS Version/Date on the right.

Regardless of why you need it, finding your BIOS (Basic Input Output System) version on Windows 11 and Windows 10 is extremely easy. You either use a graphical tool to see the version number or run a command from Command Prompt. We’ll show you various ways to get to your current BIOS version number.

Using System Information (Graphical Method)

On your keyboard, press the Windows + R keys. This will open the Run utility on your PC. Type msinfo32 in the text field and click OK.

"msinfo32" typed in Run dialog box on Windows.

Alternatively, you can simply open the Start menu and search for System Information.

This will automatically search within the System Information app and highlight every detail related to your PC’s BIOS.

Using DirectX Diagnostic Tool (Graphical Method)

Press Windows + R on your keyboard. In the Run utility, type dxdiag and click OK. The DirectX Diagnostic Tool will appear on your desktop.

"dxdiag" typed in Run dialog box on Windows.

In the System tab, find the System Information section. The BIOS parameter displayed in the list will show you the version installed on your computer.

From Command Prompt (Command-Line Method)

Press Windows + R on your keyboard to open the Run utility. Type cmd and press the Enter key.

"cmd" typed in Run dialog box on Windows.

On a Windows 11 PC, this will launch the Terminal app with a tab opened for Command Prompt by default. If you’re on Windows 10 and haven’t installed Terminal, it will open the old-style Command Prompt window. The commands will be the same, though.

In the command line, paste the following command and press Enter:

wmic bios get smbiosbiosversion

BIOS version listed in Command Prompt.

Command Prompt will directly display your BIOS version, as demonstrated in the above screenshot.

By Booting Into BIOS

If your PC doesn’t turn on and you can’t use the above methods, enter your machine’s BIOS itself to find the version number. Here’s how to do that.

Press the Windows + I keys on your keyboard to launch the Settings app.

On Windows 11, go to System > Recovery. If you’re on Windows 10, go to Update & Security > Recovery.

"Recovery" highlighted in Windows Settings.

Find the Advanced startup option and click the Restart now button.
