Before diving into complex fixes, it’s best to start with basic checks and simple troubleshooting. This approach saves time and often resolves the problem quickly.

Follow the steps below carefully, and your Windows 10 update should work smoothly again.

Quick Note: Prerequisites and Basic Checks

  • Stable Internet Connection: Ensure your PC is connected to the internet. Updates need a reliable connection to download files.
  • Enough Disk Space: Check that your system drive (usually C:) has at least 15 GB free to install updates.
  • Windows Version: Make sure your Windows 10 version is supported for updates.
  • Restart Your PC: Sometimes a simple restart clears temporary glitches affecting updates.

Step 1: Run the Windows Update Troubleshooter

The Windows Update Troubleshooter is a built-in tool designed to detect and fix common update problems automatically.

  1. Click on the Start menu and select Settings (gear icon).
  2. Go to Update & Security and then select Troubleshoot from the left panel.
  3. Click Additional troubleshooters.
  4. Select Windows Update, then click Run the troubleshooter.
  5. Follow the on-screen instructions and wait for the process to complete.

This tool will scan your system and attempt to fix issues related to update errors, including error 0x80240fff.

Step 2: Clear Windows Update Cache

Corrupted update files can cause errors. Clearing the update cache forces Windows to download fresh files.

  1. Press Windows + R keys to open the Run dialog box.
  2. Type services.msc and press Enter to open Services.
  3. Find the service named Windows Update in the list.
  4. Right-click it and select Stop.
  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 Services, right-click Windows Update, and click Start.

After clearing the cache, try running Windows Update again. This step removes any corrupted data blocking the update process.

Step 3: Reset Windows Update Components Manually

If clearing the cache doesn’t work, resetting update components can help fix deeper system issues.

  1. Open Command Prompt as an administrator:
    • Click Start, 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 update folders to force Windows to recreate them, and then restart the services.

Step 4: Check Date and Time Settings

Incorrect date and time settings can cause update errors by confusing Windows servers.

  1. Right-click the clock on the taskbar and select Adjust date/time.
  2. Make sure Set time automatically and Set time zone automatically are turned on.
  3. If they are already on, toggle them off and on again to refresh the settings.
  4. Restart your PC and try updating again.

Step 5: Disable Third-Party Antivirus Temporarily

Sometimes, antivirus software blocks Windows updates mistakenly. Disabling it temporarily can help identify if it’s causing the issue.

  1. Locate your antivirus icon in the system tray (bottom-right corner).
  2. Right-click the icon and choose the option to disable or pause protection.
  3. Try running Windows Update again.
  4. Remember to re-enable antivirus software after the update process.

Alternative Method: Use the Windows Update Assistant

If the built-in update process fails, you can use the Windows Update Assistant tool to manually install updates.

  1. Go to the official Microsoft Windows 10 download page.
  2. Download the Windows Update Assistant tool.
  3. Run the tool and follow the on-screen steps to update your system.

This method bypasses some update components and can resolve persistent errors.
