Run the Windows Update Troubleshooter

Reset Windows Update Components

Resetting the Windows Update components can often fix underlying issues. To do this:

  2. Run the following commands one by one, pressing Enter after each:

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

  3. Rename the SoftwareDistribution and Catroot2 folders:

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

  4. Restart the services in reverse order:

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

Check Your Internet Connection

Ensure you have a stable internet connection. You can try restarting your router or modem.

Free Up Disk Space

Windows Updates require sufficient disk space to download and install. Delete unnecessary files and programs to free up space.

Temporarily Disable Antivirus Software

Antivirus software can sometimes interfere with Windows Update. Temporarily disable your antivirus and attempt the update again. Remember to re-enable it afterward.

Run System File Checker (SFC)

The SFC tool scans for and repairs corrupted system files. Open Command Prompt as administrator and run: sfc /scannow.

Perform a Clean Boot

A clean boot starts Windows with minimal drivers and startup programs, which can help isolate the cause of the error. To perform a clean boot:

  1. Press Windows key + R, type msconfig, and press Enter.
  2. Go to the Services tab and check the box for "Hide all Microsoft services."
  3. Click "Disable all".
  4. Go to the Startup tab and click "Open Task Manager".
  5. Disable all startup items.
  6. Restart your computer.

If the error is resolved in clean boot mode, it suggests a third-party program or service is causing the issue. Try re-enabling services and startup items one by one to identify the culprit.

Update Drivers

Outdated drivers can contribute to system instability. Check for driver updates for your network adapter and other hardware components from the manufacturer's website or through Device Manager.

If none of these solutions work, you may need to consider a more advanced troubleshooting approach such as reinstalling Windows. Remember to back up your important data before attempting any major system changes.
