This guide will walk you through easy-to-follow solutions in a step-by-step manner. Each step explains why it’s important and how to perform it.

By following this guide, you can fix error code 0x80072ef3 and ensure your Windows 11 updates run smoothly again.

Quick Note: What to Check Before You Start

  • Internet Connection: Make sure your PC is connected to the internet and your connection is stable. This error often happens due to connectivity issues.
  • Date and Time Settings: Incorrect date and time on your computer can cause problems with connecting to update servers.
  • Windows Update Service: Ensure Windows Update service is running. If it’s stopped, updates won’t download.
  • Antivirus and Firewall: Sometimes security software blocks update servers. Temporarily disable them if needed.

Step 1: Restart Your Computer and Router

Sometimes, a simple restart can fix temporary glitches affecting network or system services. Restarting your PC refreshes system processes, and rebooting the router can reset your internet connection.

  1. Click the Start menu, then select Power and choose Restart.
  2. After your PC restarts, power off your router by unplugging it, wait 30 seconds, and plug it back in.
  3. Once your internet is back online, try running Windows Update again.

Step 2: Check and Correct Date and Time Settings

If your computer’s date and time are incorrect, Windows may have trouble contacting update servers securely.

  1. Right-click the date and time on the taskbar and select Adjust date and time.
  2. Turn on Set time automatically and Set time zone automatically.
  3. If these are already on, click Sync now under Additional settings to force a time sync.
  4. Restart your computer and try updating again.

Step 3: Run the Windows Update Troubleshooter

Windows includes a built-in tool that can automatically detect and fix common update problems.

  1. Open Settings by pressing Windows + I.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen instructions. The troubleshooter will attempt to identify and fix issues.
  5. After it finishes, restart your PC and check for updates again.

Step 4: Reset Windows Update Components Manually

If the issue persists, resetting Windows Update components can fix corruption or configuration problems.

This involves stopping update services, deleting temporary update files, and restarting services.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following 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

These commands stop update services, rename folders that store update files (forcing Windows to recreate them), then restart the services.

After completing this, restart your PC and try updating again.

Step 5: Temporarily Disable Antivirus and Firewall

Sometimes, third-party antivirus or firewall software blocks Windows Update from connecting to Microsoft servers.

Try disabling your antivirus and firewall temporarily, then check if the update works.

  1. Open your antivirus program and look for an option to disable protection temporarily.
  2. To disable Windows Firewall, go to Settings > Privacy & Security > Windows Security > Firewall & Network Protection.
  3. Select your active network and turn off the firewall.
  4. Try running Windows Update again.
  5. Remember to re-enable your antivirus and firewall after testing.

Step 6: Use the System File Checker (SFC) Tool

Corrupted system files can interfere with updates. The System File Checker scans and repairs these files.

  1. Open Command Prompt as administrator (see Step 4).
  2. Type sfc /scannow and press Enter.
  3. Wait for the scan to complete. It may take several minutes.
  4. If it finds and fixes issues, restart your PC and try updating again.

Step 7: Check Your Network Settings

This error can occur if your network has incorrect DNS settings or proxy configurations.

  1. Open Settings and go to Network & Internet > Advanced network settings > More network adapter options.
  2. Right-click your active network adapter and select Properties.
  3. Double-click Internet Protocol Version 4 (TCP/IPv4).
  4. Make sure Obtain DNS server address automatically is selected.
  5. If you want to use a custom DNS like Google’s, enter 8.8.8.8 and 8.8.4.4.
  6. Click OK and close all windows.
  7. Also, check Settings > Network & Internet > Proxy and ensure no unwanted proxy is enabled.

After adjusting, restart your PC and try updating.

Advanced Option: Use the Media Creation Tool

If none of the above steps work, you can use the Media Creation Tool from Microsoft to update Windows 11 manually.

This tool downloads the latest Windows version and installs it without affecting your files.
