This error usually happens when Windows Update fails to install certain files correctly. It can be frustrating, but there are several straightforward solutions to fix it.

In this article, we will walk you through simple, step-by-step methods to resolve the error and get your Windows 11 updates working again.

Follow each step carefully, and you should be able to fix the update problem without needing advanced technical skills.

Quick Note Before You Begin

Before diving into fixes, make sure your internet connection is stable. A poor connection can interrupt updates and cause errors.

Also, check if your device has enough free disk space. Windows updates need room to download and install files.

Lastly, it’s a good idea to temporarily disable any third-party antivirus or firewall software, as these can sometimes block updates.

Step 1: Run the Windows Update Troubleshooter

The built-in Windows Update Troubleshooter can automatically detect and fix many common update problems. Here's how to use it:

1. Click on the Start button and select Settings.
2. Go to System and then click on Troubleshoot.
3. Select Other troubleshooters.
4. Find Windows Update and click Run.
5. Wait for the troubleshooter to scan your system and follow any instructions it provides.

This tool helps by resetting update components and clearing temporary files that may cause issues.

Step 2: Clear the Windows Update Cache Manually

Sometimes, corrupted files in the update cache cause errors. Clearing this cache forces Windows to download fresh files.

Follow these detailed steps:

1. Press Windows + R keys on your keyboard to open the Run dialog box.
2. Type services.msc and press Enter.
3. In the Services window, scroll down and find Windows Update.
4. Right-click Windows Update and select Stop to pause the service.
5. Open File Explorer and navigate to C:WindowsSoftwareDistributionDownload.
6. Select all files and folders inside the Download folder and delete them.
7. Go back to the Services window, right-click Windows Update again, and select Start to resume the service.

Deleting these files removes old update data that might be causing the error.

Step 3: Reset Windows Update Components Using Command Prompt

If clearing the cache didn’t work, manually resetting Windows Update components can help. This method involves running a few commands to fix update settings.

Here’s how to do it step-by-step:

1. Click the Start button, type cmd, then right-click Command Prompt and select Run as administrator.
2. In the Command Prompt window, type the following commands one by one. Press Enter after each command:

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

These commands stop update services, rename the folders containing update files (which acts as a reset), and then restart the services.

Step 4: Check for System File Corruption with SFC and DISM

Corrupted system files can interfere with updates. Windows provides tools to scan and repair these files.

Follow these steps:

1. Open Command Prompt as an administrator (as shown in Step 3).
2. Type the following command and press Enter:

sfc /scannow

This will scan your system for corrupted files and automatically fix them if possible.

If problems persist, run the Deployment Image Servicing and Management (DISM) tool:

3. In the same Command Prompt window, 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

DISM scans your Windows image and repairs any issues that could block updates.

Step 5: Temporarily Disable Antivirus Software

Third-party antivirus programs sometimes interfere with Windows Update. Temporarily turning them off can help identify if they are the cause.

Be sure to re-enable your antivirus after the update process completes to keep your PC protected.

Alternative Methods

If the above steps don’t work, consider these options:

• Use the Windows Update Assistant: Download and run the official Update Assistant from Microsoft’s website to manually install updates.
• Perform a Clean Boot: This starts Windows with minimal drivers and startup programs, helping you identify if third-party software is causing the issue.
