Add Windows Update sites to your security software's exception list

If you continue to receive this error, a program running on your computer may be preventing Windows Update Services (SVCHOST) from accessing the Internet. Programs that might do this include firewalls, antispyware software, web accelerators, Internet security or antivirus programs, and proxy servers. To resolve this problem, you may have to add the Windows Update website addresses to the blocking program's exceptions or "allow" list, or you may have to enable the Windows Update Service to connect to the Internet through port 80 or port 443.

Windows Firewall is included with these versions of Windows and should already include the Windows Update sites in its exceptions list. If you use a different firewall or any other third-party security software, you should refer to the software publisher's documentation to see how to add the Windows Update sites to your firewall exceptions list. The Windows Update sites are as follows:
  • http://*.update.microsoft.com
  • https://*.update.microsoft.com
  • http://download.windowsupdate.com
