How to Fix Windows Remediation Service Failed to Start Error on Windows 11

If you have encountered the “Windows Remediation Service failed to start” error on your Windows 11 device, you are not alone. This issue can prevent certain security features from working correctly. Fortunately, there are straightforward ways to fix it.

The Windows Remediation Service is part of the system’s security framework. When it fails, some system protections might be compromised.

This article will guide you through simple steps to resolve this issue. Each step is explained in detail to help users of all experience levels.

By following these instructions, you can restore the service and ensure your Windows 11 system stays secure.

Quick Note: Prerequisites and Checks Before You Start

Before diving into fixes, please make sure of the following:

  • Your Windows 11 system is updated to the latest version. Updates often fix bugs causing service failures.
  • You have administrative privileges on your PC. Many fixes require administrator access to make system changes.
  • Check if your antivirus or security software is interfering. Sometimes third-party software blocks Windows services.
  • Restart your computer once before starting troubleshooting. This simple step can resolve temporary glitches.

Step 1: Restart the Windows Remediation Service Manually

Sometimes, the service might just be stopped or stuck. Restarting it manually can fix temporary issues.

  1. Press Windows + R keys to open the Run dialog box.
  2. Type services.msc and press Enter. This opens the Services window.
  3. Scroll down and find Windows Remediation Service or Windows Remediation Service (WerSvc).
  4. Right-click it and select Start if it’s stopped. If already running, choose Restart.
  5. Close the window and check if the error still appears.

Why this is important: Restarting the service can clear any stuck processes or errors causing it to fail.

Step 2: Check and Set the Service Startup Type

The service might be disabled or set to manual, causing it not to start automatically with Windows. Setting it to automatic can help.

  1. Open the Services window again by pressing Windows + R, typing services.msc, and pressing Enter.
  2. Find the Windows Remediation Service.
  3. Right-click and select Properties.
  4. In the General tab, find the Startup type dropdown.
  5. Set it to Automatic.
  6. Click Apply and then OK.
  7. Restart your computer to apply the changes.

Why this is important: Automatic startup ensures the service runs whenever Windows boots, preventing the error from occurring again.

Step 3: Run System File Checker (SFC) to Repair Corrupted Files

Corrupted system files can cause services to fail. The System File Checker tool scans and repairs these files.

  1. Click the Start button and type cmd.
  2. Right-click Command Prompt and select Run as administrator.
  3. In the command window, type the following command and press Enter:
sfc /scannow

This process may take some time. Wait until it completes and follow any on-screen instructions.

Why this is important: Repairing system files can fix issues underlying the service failure, ensuring Windows components work correctly.

Step 4: Use DISM Tool to Fix Windows Image

If SFC doesn’t resolve the problem, the Deployment Image Servicing and Management (DISM) tool can repair the Windows system image.

  1. Open Command Prompt as administrator again.
  2. Type these commands one by one, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Wait patiently as these commands complete. After finishing, restart your PC.

Why this is important: DISM fixes deeper issues in the Windows system image that SFC can’t repair on its own.

Step 5: Disable Third-Party Antivirus Temporarily

Sometimes, antivirus programs interfere with Windows services. To check if this is the cause:

  1. Temporarily disable your antivirus or security software.
  2. Restart your PC.
  3. Check if the Windows Remediation Service starts without errors.
  4. If the error is gone, adjust your antivirus settings to whitelist Windows services or consider switching to a different program.

Why this is important: Antivirus interference is a common cause of Windows service errors and disabling it helps isolate the problem.

Alternative Method: Reset Windows Update Components

Sometimes the remediation service is linked to Windows Update components. Resetting these can help.

  1. Open Command Prompt as administrator.
  2. Run these commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Restart your PC after running these commands.

Why this is important: Resetting update components fixes issues that might prevent the remediation service from starting properly.
