This post shows you how to check current BIOS version in a Windows 10/8.1/8/7 computer, using Windows Registry, WMI Command, System Information Tool (MSINFO32.exe) or DirectX Diagnostic Tool (DXDiag). BIOS stands for Basic Input/Output System and is a type of firmware that is built into the hardware, used during and for the booting process of a computer.
Jul 29, 2019 For bios and drivers with Dell, use Dell Command Update. If you stay with version 2.4, you can do this from the CLI (or script it of course). Pull the logs to a central store for review It has worked well for us in getting systems ready for 1903. Everything from the last 6 years works fine and now upgrades cleanly to 1903. I wrote a task to check for specific model Dell machines, if they had less than the latest version of their BIOS, and then deploy the updates to them.

Check BIOS version
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 questions. 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 windows, type the following and hit Enter:
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_MACHINEHARDWAREDESCRIPTIONSystem
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 some 3rd-party system information tool like Speccy to see your BIOD version or see it when you enter your machines BIOS setup by pressing F10/F12 keys during boot-time.

Your BIOS version number isn't something you need to keep tabs on at all times. The main reason you'd want to check what version it's at is if you're curious if there's a BIOS update available.
Like most things in the technology world, your motherboard software (BIOS) occasionally gets updated, sometimes to fix bugs and other times to add new features.
As part of some hardware troubleshooting processes, especially those that involve new RAM or a new CPU that won't work correctly, updating BIOS to the latest version is a good thing to try.
Below are six different methods for checking the BIOS version installed on your motherboard:
Methods 1 and 2 are best if your computer isn't working properly. They are operating system independent.
Methods 3, 4, 5, and 6 are more convenient ways to check the BIOS version, require your computer to be working, and work in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP.
Method 1: Reboot Your Computer & Pay AttentionDell Bios Version List
The 'traditional' way to check the BIOS version on a computer is to watch for the version notation that appears on the screen during the POST as your computer starts to boot.
The reboot method is great when you don't have the benefit of a working computer and can't try one of the more convenient methods below.
However, it can get really frustrating restarting your computer over and over if you keep missing the BIOS version notation. The POST results screen is usually really fast, especially as computers get faster and decrease boot time.
Method 2: Let the BIOS Update Tool Tell You
Updating BIOS isn't something you do manually, not completely anyway. In most cases, you'll use a special BIOS update tool supplied by your computer or motherboard manufacturer to do the job.
More often than not, this tool will clearly show the current BIOS version that's installed, so even if you're not quite ready to update BIOS, or not sure you need to, the BIOS update tool can be used just to check the current version.
You'll first need to locate the online support for your computer or motherboard maker and then download and run the tool. No need to actually update anything, so skip those later steps in whatever instructions are provided.
This method works when your computer isn't starting properly only if the BIOS update tool for your motherboard is bootable. In other words, if the BIOS update program supplied only works from within Windows, you'll have to stick to Method 1.
Method 3: Use Microsoft System Information (MSINFO32)
A much easier way to check the BIOS version running on your computer's motherboard is via a program called Microsoft System Information.
Not only does this method not require any restarting of your computer, it's already included in Windows, meaning there's nothing to download and install.
Here's how to check the BIOS version with Microsoft System Information:
Microsoft System Information is a great tool but it doesn't always report a BIOS version number. If it didn't for your computer, a similar program not made by Microsoft should be the next thing you try.
Method 4: Use a 3rd Party System Information Tool
If Microsoft System Information didn't get you the BIOS version data you need, there are several system information tools out there you can try instead, many that are much more thorough than MSINFO32.

Here's how to do it:
Dell System Bios Update
The Brand listed under BIOS isn't usually something that's worthwhile to know. The BIOS update tool and data file you need will come from your computer or motherboard maker, listed as Manufacturer, and will be specific to your motherboard model, listed as Model.
If Speccy or another 'sysinfo' tool doesn't work out for you, or you'd rather not download and install software, you have a couple other methods for checking your computer's BIOS version.
Method 5: Run a Command Prompt Command
A simple command can be used to print the BIOS version in Command Prompt. You might try this before the slightly more advanced method below, but only after trying the graphical programs above.
You can also enter the systeminfo | findstr 'BIOS Version' command into Command Prompt to find the BIOS version information as its reported in the System Information tool explained above.
Method 6: Dig It up in the Windows Registry
Last but not least, and probably not that surprising to those of you in the know, a lot of information about BIOS can be found logged in the Windows Registry.
Not only is the BIOS version usually clearly listed in the registry, so is often your motherboard's maker and your motherboard model number.
Here's where to find it:
No changes are made to registry keys in the steps below but if you're afraid you might make unintentional changes to this very important part of Windows, you can always back up the registry, just to be safe.

The Windows Registry can seem scary but so long as you're not changing anything, it's perfectly harmless to dig around.
Did you accidentally make changes in Windows Registry? It's easy to reverse them if you backed up the registry to a REG file. see How to Restore the Windows Registry if you need help.
