Disable Antivirus Temporarily

Temporarily disable your antivirus software to see if it's interfering with Windows Update. Remember to re-enable it after troubleshooting.

Update Network Drivers

Outdated network drivers can hinder connectivity. Check the manufacturer's website for the latest drivers compatible with your operating system and install them.

Run System File Checker

The System File Checker (SFC) tool scans for corrupted system files and attempts repairs:

  • Open Command Prompt as an administrator.

  • Type sfc /scannow and press Enter.

  • Allow the scan to complete, which may take some time.

Reset Windows Update Components
