Updating BIOS or UEFI on a Windows 10 PC is a manufacturer-specific firmware operation. Use the exact firmware for your computer or motherboard and update only when the release notes provide a reason to do so.
Find the Current Firmware

msinfo32. - Open System Information.
- Record the system or motherboard model and BIOS version/date.
Verify the Correct Update
- Open the manufacturer’s official support site.
- Find the support page for the exact model.
- Read the BIOS release notes.
- Confirm the update is appropriate for your hardware before downloading it.
Prepare Safely
- Back up important files.
- Save your BitLocker or device-encryption recovery key.
- Connect reliable AC power and avoid starting a firmware update during an unstable power situation.
- Read the manufacturer’s flashing instructions completely.
Flash the BIOS or UEFI
- Use only the manufacturer’s supported update method.
- Confirm the model and version again.
- Start the firmware update.
- Do not power off or interrupt the computer until the manufacturer reports completion.
Windows 10 Support Status
Standard Windows 10 support ended October 14, 2025. Firmware updates may still be available from a manufacturer, but BIOS updates do not extend Microsoft’s Windows support lifecycle. Plan a supported operating-system migration where appropriate.
Summary
Use the exact manufacturer’s firmware and update method, with backups, recovery information, and stable power in place. Never interrupt a BIOS/UEFI flash.
