To check your BIOS version in Windows 10, press Win + R, type msinfo32, and press Enter. In System Information, look at BIOS Version/Date in the System Summary. It shows the maker, version number, and release date, such as “1.24.0, 3/14/2026”. You can also use a PowerShell command, shown below.
Windows 10 reached end of support on October 14, 2025. Consumer Extended Security Updates (ESU) now run until October 12, 2027. These steps also work in Windows 11.
Quick Answer
Win + R > msinfo32 > Enter > read BIOS Version/Date.
Method 1: System Information
- Press Win + R.
- Type msinfo32 and press Enter.
- With System Summary selected, find BIOS Version/Date.
- Also note BIOS Mode (UEFI or Legacy) and System Model, which you’ll need to find updates.
Method 2: PowerShell
- Right-click Start and open Windows PowerShell.
- Run
Get-CimInstance Win32_BIOS. - Read SMBIOSBIOSVersion (the version) and Manufacturer.
The older wmic bios get smbiosbiosversion command still works on many Windows 10 PCs, but WMIC is deprecated, so the PowerShell command is the better habit.
Method 3: In the Firmware or PC Maker’s App
- The version is shown on the main screen when you open the BIOS/UEFI.
- PC maker utilities (for example, the ones from Dell, HP, and Lenovo) show the BIOS version and offer updates.
What to Do With the Version
| Goal | Next step |
|---|---|
| Check for an update | Enter your model on the PC maker’s support site and compare versions |
| Troubleshoot compatibility | Note the version for support staff or forums |
| Enable a feature (such as TPM or virtualization) | Newer firmware may add or fix the option |
Update the BIOS only with the maker’s official tool and file, with the laptop plugged in. A failed update can stop the PC from starting. Driver updates are a separate, lower-risk task; see how to update drivers.
Troubleshooting
- msinfo32 shows a generic value: Custom-built PCs may list the motherboard maker’s version string. Check the motherboard model under BaseBoard Product.
- System Information takes a while to load: That’s normal; it gathers details when it opens.
- You need to open the firmware: See how to access the BIOS from Windows.
Frequently Asked Questions
Should I update my BIOS?
Only if the update fixes a problem you have, adds support you need, or is a security fix from your PC maker.
Can I check the BIOS version without restarting?
Yes. msinfo32 and PowerShell both show it from inside Windows.
What does BIOS Mode Legacy mean?
The PC boots the older way. Windows 11 requires UEFI with Secure Boot capability.
Summary
- Press Win + R and run msinfo32.
- Read BIOS Version/Date.
- Or run Get-CimInstance Win32_BIOS in PowerShell.
- Update only with your PC maker’s official tool.
