Check BIOS version in Windows 11
You may need to check your BIOS version if you plan to update the BIOS. Of course, whether you want to do it or whether you should do it is another question. Anyway, there are several ways you can do this. Lets us have a look at them.
1] Using WMI Commands
You can use Windows Management Instrumentation to find out the details of your BIOS. To do so, open an elevated command prompt window, type the following and hit Enter:
wmic bios get biosversion
2] Using MSINFO32
The built-in MSINFO32 or System Information Tool displays this information under System Summary. To open this tool, Run msinfo32 and hit Enter.
3] Using Registry Editor
When Windows loads, it stores the BIOS information and other details under the following registry key:
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System
Here you will see the details under System. You will also see additional details under SystemBiosDate, SystemBiosVersion, VideoBiosDate and VideoBiosVersion subkeys.
To see the BIOS version Run regedit and navigate to the mentioned registry key.
4] Using DXDiag
DirectX Diagnostic Tool or DXDiag.exe is basically meant to help you troubleshoot DirectX issues. But if you Run dxdiag to open it, you will see the BIOS version mentioned under the System tab.
Of course, apart from this, you can also use a 3rd-party system information tool like Speccy to view your BIOS version, or check it in your machine’s BIOS setup by pressing F10/F12 during boot time.
