How to Fix Unauthorized Changes to Firmware Error on Windows 11: Step-by-Step Guide

Encountering an “Unauthorized Changes to Firmware” error on Windows 11 can be frustrating. This message usually appears when your system detects unexpected modifications to the firmware. Firmware is a critical part of your computer’s hardware that controls low-level operations.

This guide will help you understand why this error occurs and how to fix it properly. Follow each step carefully to restore your system’s normal functioning. No advanced knowledge is required—just a bit of patience and attention to detail.

By fixing this issue, you can ensure your device remains secure and stable. Let’s begin with some quick checks before diving into the troubleshooting steps.

Whether you are a beginner or a seasoned user, these instructions are designed to be clear and easy to follow.

Quick Note: Prerequisites and Initial Checks

  • Check your system’s warranty and support status: Before making changes, confirm that your device is supported and under warranty. Firmware issues sometimes require professional help.
  • Backup your data: Although these steps are safe, it’s always a good idea to back up important files to avoid any accidental loss.
  • Ensure your Windows 11 is up to date: Updates often include fixes for firmware-related problems.
  • Use an administrator account: You need admin rights to perform most of these steps.

Step 1: Restart Your Computer

Sometimes, simply restarting your PC can clear temporary glitches causing firmware errors. This basic step resets hardware states and clears minor bugs.

To restart:

  1. Click on the Start menu (Windows icon).
  2. Select Power.
  3. Click Restart.

Once your system restarts, check if the error persists.

Step 2: Check for Windows Updates

Firmware errors can sometimes be resolved by installing the latest Windows updates. Microsoft regularly releases patches that improve compatibility and security.

To update Windows:

  1. Open Settings by pressing Windows + I.
  2. Click on Windows Update in the left sidebar.
  3. Click Check for updates.
  4. If updates are available, click Download and install.
  5. After installation, restart your computer.

Step 3: Disable Secure Boot Temporarily

The “Unauthorized Changes to Firmware” error can sometimes be triggered by Secure Boot—a security feature designed to prevent unauthorized firmware or software from loading during startup.

Temporarily disabling Secure Boot can help identify if it’s causing the problem. However, be cautious: turning off Secure Boot reduces your system’s security, so turn it back on after troubleshooting.

To disable Secure Boot:

  1. Restart your PC and enter the BIOS/UEFI settings. This is usually done by pressing a key like F2, Delete, or Esc immediately after powering on. Check your manufacturer’s guide for the exact key.
  2. In the BIOS menu, locate the Secure Boot option—usually under Security or Boot tab.
  3. Change the Secure Boot setting to Disabled.
  4. Save changes and exit the BIOS. Your system will restart.

Check if the error appears after disabling Secure Boot. If the error disappears, Secure Boot might be rejecting legitimate firmware changes, or your firmware might need updating.

Step 4: Update Your Firmware (BIOS/UEFI)

Outdated firmware can trigger unauthorized change errors because Windows detects differences between expected and actual firmware versions.

Updating your BIOS or UEFI to the latest version often resolves compatibility and security issues.

Before you update:

  • Identify your motherboard or laptop model.
  • Visit the manufacturer’s official website.
  • Download the latest BIOS/UEFI update file and follow their precise instructions.

Important: Firmware updating is sensitive. Follow manufacturer instructions carefully. Do not turn off your PC during the update.

Step 5: Run System File Checker and DISM

Corrupted system files can cause Windows to misinterpret firmware status. Running built-in repair tools can fix these files.

To run System File Checker (SFC) and Deployment Image Servicing and Management (DISM):

  1. Press Windows + S and type cmd.
  2. Right-click Command Prompt and select Run as administrator.
  3. In the command window, type the following commands one by one and press Enter after each:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Wait for each process to complete. These tools will scan and repair corrupted Windows files.

Step 6: Reset BIOS to Default Settings

If you recently changed BIOS settings, those changes might cause conflicts with Windows security features.

Resetting BIOS to default can remove unauthorized firmware change errors caused by incorrect configurations.

To reset BIOS:

  1. Restart your PC and enter BIOS/UEFI setup (similar to Step 3).
  2. Look for an option like Load Setup Defaults or Reset to Default.
  3. Select it and confirm.
  4. Save changes and exit BIOS.

Your computer will restart with default BIOS settings.

Alternative Method: Use Windows Recovery Environment

If the error prevents Windows from booting normally, you can use the Windows Recovery Environment (WinRE) to troubleshoot.

To enter WinRE:

  1. Turn off your PC.
  2. Power it on and immediately press the Power button again to force shutdown while Windows loads. Repeat this 2-3 times.
  3. Windows will enter recovery mode automatically.
  4. Choose Troubleshoot > Advanced Options > Startup Repair.

This automated tool can fix startup and firmware-related issues.
