Windows Update error 0x80246005 in Windows 11 interrupts the update process and leaves your device without the latest security and feature updates. This error often points to issues with update files, system components, or security software interfering with the update service. Addressing this error restores the ability to download and install updates, which keeps your system secure and stable.

Repair Windows System Files and Update Components

Step 1: Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator. This gives you the necessary permissions to run system-level commands.

Step 2: In the Command Prompt window, run the System File Checker to scan for and repair corrupted system files. Enter:

sfc /scannow

This process may take several minutes. Wait for it to complete and follow any on-screen instructions if issues are detected.

Step 3: Next, use the Deployment Imaging Service and Management Tool (DISM) to check and repair Windows image corruption. Enter the following commands one at a time, pressing Enter after each:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands will identify and fix deeper issues that can prevent Windows Update from functioning correctly. Allow each command to finish before proceeding to the next.

Clear Windows Update Cache and Temporary Files

Step 1: Open File Explorer and navigate to C:\Windows\SoftwareDistribution\Download. This folder contains cached update files that may be corrupted.

Step 2: Select all files and folders inside the Download folder and delete them. If prompted, provide administrator permission. Removing these files forces Windows Update to re-download fresh update packages.

Step 3: Restart your computer to ensure changes take effect and the update services reset.

Disable Antivirus and Firewall Temporarily

Step 1: Third-party antivirus software and firewalls can block Windows Update components. Temporarily disable any non-Microsoft antivirus programs. If you use Windows Defender, open Windows Security, go to Virus & Threat Protection settings. Turn off Real-time protection.

Step 2: Open Windows Security again, select Firewall & network protection, and turn off the firewall for your active network profile. Remember to re-enable both antivirus and firewall after troubleshooting to maintain system security.

Run Windows Update Troubleshooter

Step 1: Go to Settings > System > Troubleshoot > Other troubleshooters.

Step 2: Find Windows Update in the list and click Run. The troubleshooter will automatically scan for and attempt to fix common update problems, including service misconfigurations and missing files.

Step 3: Follow any on-screen recommendations provided by the troubleshooter. If prompted, allow the tool to restart services or your device.

Reset Windows Update Services Manually

Step 1: Open Command Prompt as administrator.

Step 2: Stop Windows Update-related services by entering these commands one at a time:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver

Step 3: Rename the SoftwareDistribution and Catroot2 folders to force Windows to create fresh copies:

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old

Step 4: Restart the services you stopped earlier:

net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Step 5: Restart your computer and try to run Windows Update again.

Use Windows Media Creation Tool for Update Repair

Step 1: If update errors persist, download the latest Windows 11 installation media from the official Microsoft website. Search for “Windows 11 Media Creation Tool” and follow the prompts to download the tool.

Step 2: Run the tool and choose Upgrade this PC now. This process repairs and updates your Windows installation without deleting personal files or installed applications. Ensure you have at least 40GB of free space on your system drive before starting.

Step 3: Follow on-screen instructions to complete the update. After the process, check Windows Update to verify that updates now install correctly.

Additional Checks and Maintenance

  • Verify your system date and time are set correctly. Incorrect settings can block update downloads.
  • Disconnect unnecessary external drives or USB devices during updates.
  • Ensure a stable internet connection throughout the update process.
  • After troubleshooting, re-enable antivirus and firewall protection.

Consistently applying these methods resolves error 0x80246005 and restores your device’s ability to receive updates, which directly improves system security and reliability.

Regular maintenance and prompt troubleshooting keep Windows 11 running smoothly and secure. If issues persist, contacting Microsoft Support through the Get Help app provides direct assistance for complex cases.
