How to Update the BIOS on Windows 10

To update the BIOS on a Windows 10 PC, first check your current version: press Windows + R, type msinfo32, and look at BIOS Version/Date and System Model. Then get the update from your PC or motherboard maker. On most laptops and prebuilt desktops, the easiest way is the maker’s support app (such as Dell SupportAssist, HP Support Assistant, or Lenovo Vantage), or downloading the BIOS update file from the support site and running it in Windows. Plug in your laptop, suspend BitLocker, and don’t turn off the PC while it updates.

A BIOS update can fix bugs, add hardware support, and patch security issues, but a failed update can stop a PC from starting. Only update if there’s a reason to, and follow these steps carefully.

Should you update your BIOS?

• Yes, if the update fixes a problem you have, adds support for new hardware (like a newer CPU), includes security fixes, or your PC maker recommends it.
• Maybe not, if everything works fine and the update notes don’t apply to you.

Step 1: Check your current BIOS version

1. Press Windows + R, type msinfo32, and press Enter.
2. In System Summary, note the System Model (or BaseBoard Product for custom PCs) and BIOS Version/Date.

Step 2: Prepare your PC

• Plug in the power adapter. Many laptops refuse to update below a certain battery level.
• Suspend BitLocker: Search for Manage BitLocker in Start and click Suspend protection. Otherwise you may be asked for your recovery key after the update. See how to find your BitLocker recovery key.
• Save your work and close apps.
• Back up important files, just in case.

Step 3A: Update a laptop or prebuilt desktop

1. Open your maker’s support app, if installed, and check for updates. It downloads and installs the BIOS update for your exact model.
2. Or go to the maker’s support website, enter your model or serial number, and open the BIOS or Firmware section of downloads.
3. Download the latest BIOS update and read the release notes.
4. Run the downloaded file and follow the prompts. The PC restarts and updates, usually in 2 to 10 minutes.
5. Don’t press keys or turn off the PC until Windows loads again.

Some PCs also receive BIOS updates through Windows Update as optional firmware updates.

Step 3B: Update a custom-built PC (motherboard)

1. Find your motherboard model in msinfo32 under BaseBoard Product.
2. Download the BIOS file from the motherboard maker’s support page (ASUS, MSI, Gigabyte, ASRock, and others).
3. Unzip it and copy the file to a USB flash drive formatted as FAT32.
4. Restart and enter the BIOS (usually Delete or F2).
5. Open the built-in update tool, such as EZ Flash, M-Flash, or Q-Flash, select the file, and start the update.

Some boards also have a BIOS Flashback button that updates from USB without a working CPU. Check your manual for the exact file name it needs.

After the update

• Check msinfo32 to confirm the new version.
• Re-enable BitLocker if it didn’t resume automatically.
• Review BIOS settings like XMP/EXPO memory profiles, boot order, and virtualization, since updates can reset them to defaults. See how to enable virtualization if needed.

If something goes wrong

• PC restarts several times: This can be normal during an update. Wait at least 10 minutes.
• Update failed or PC won’t boot: Many modern PCs have a backup BIOS or recovery mode. Check your maker’s support site for BIOS recovery steps, or contact support.
