Run the Windows Update Troubleshooter

  • Press Windows key + I to open Settings.

  • Navigate to Update & Security.

  • Select Troubleshoot from the left sidebar.

  • Click on Windows Update and follow the on-screen instructions.

Check Disk Space

Ensure you have sufficient free space on your hard drive for the update process. Windows updates can require several gigabytes of space. To check disk space:

  • Open File Explorer.

  • Right-click on your primary drive (usually C:) and select Properties.

  • Review the available free space. If it's low, delete unnecessary files or move them to an external drive.

Disable Firewall and Antivirus Temporarily

Your firewall or antivirus software might be blocking the update process. Temporarily disable them and attempt the update again. Remember to re-enable them afterward.

Run System File Checker (SFC) Scan

The SFC tool scans for and repairs corrupted system files that could be causing the error. To run it:

  • Open Command Prompt as an administrator.

  • Type sfc /scannow and press Enter.

Update Drivers

Outdated drivers can sometimes lead to compatibility issues. Ensure your drivers, especially those related to network adapters, are up-to-date. You can update drivers through Device Manager or by downloading the latest versions from your computer manufacturer's website.

Reset Windows Update Components

Resetting the Windows Update components can resolve various update-related errors:

  • Open Command Prompt as an administrator.

  • Execute the following commands one by one, pressing Enter after each:

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

  • Rename the SoftwareDistribution and Catroot2 folders.

    • Type ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    • Type ren C:\Windows\System32\catroot2 Catroot2.old

  • Restart the services:

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

Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs. This can help isolate whether a third-party application is interfering with the update process. To perform a clean boot:

  • Press Windows key + R to open the Run dialog box.

  • Type msconfig and press Enter.

  • Go to the Services tab, check the box for "Hide all Microsoft services," and then click Disable All.

  • Go to the Startup tab and click Open Task Manager.

  • Disable all startup items listed there.

  • Close Task Manager and click OK on the System Configuration window. Restart your computer.

Consider a Repair Install

If other troubleshooting steps fail, you can consider performing a repair install of Windows. This process reinstalls Windows files while preserving your personal data and settings. For detailed instructions on how to perform a repair install, refer to Microsoft's support website. You can download the latest Windows 10 installation media from this link.
