Real-time Protection

Troubleshooting real-time protection issues

Symptoms: Common issues that you might experience when using real-time protection including the following:
 

Before you try anything else, make sure that your computer is connected to the Internet. You can try using the Network troubleshooter that automatically fixes some common problems that involve going online. For more information, see Why can't I connect to the Internet.
Many connection errors are caused by temporary problems involving the Internet. Wait a few minutes, and then try running Windows Update again. If you've turned on automatic updating, you can also wait and let Windows Update run on schedule.
If your computer is connected directly to the Internet or to a home network (and never connected to a network at work), you might want to configure your browser to automatically detect local area network (LAN) settings so that your computer can go online to obtain updates from Windows Update or Microsoft Update. To do this, follow these steps:
If your computer is connected directly to the Internet or to a home network (and never connected to a network at work), you might want to configure your WinHTTP proxy setting to use direct access. To do this, follow these steps:
If your computer can connect to the Internet but cannot obtain the updates from Windows Update, try to opt-in Microsoft Update so that your computer can obtain updates from Microsoft Update. To do this, follow these steps:
Note This method does not apply to Windows XP.
When there is a firewall between the Windows Update agent and the Internet, the firewall might need to be configured to allow communication for the HTTP and HTTPS ports used for Windows Update. Windows Update agent uses port 80 for HTTP and port 443 for HTTPS to obtain updates.
If your organization does not allow the ports and protocols to be open to all addresses, you can restrict access to the following sites:
  • http://windowsupdate.microsoft.com
  • http://*.windowsupdate.microsoft.com
  • https://*.windowsupdate.microsoft.com
  • http://*.update.microsoft.com
  • https://*.update.microsoft.com
  • http://*.windowsupdate.com
  • http://download.windowsupdate.com
  • http://download.microsoft.com
  • http://*.download.windowsupdate.com
  • http://wustat.windows.com
  • http://ntservicepack.microsoft.com
  • https://*.ws.microsoft.com
  • http://*.ws.microsoft.com
If the problem continues, you can use the Windows Update troubleshooter to automatically fix some common problems with Windows Update or Microsoft Update, and then run Windows Update again. To start the troubleshooter, click run now.
Sometimes, the Windows Update agent cannot connect to the Windows Update service because of corrupted Windows components. To fix such corruptions, follow these steps:
  1. Use the System File Checker tool to repair corrupted Windows files, and then run Windows Update again.
  2. If the problem continues, use the DISM or System Update Readiness (CheckSur) tool to repair Windows servicing corruptions.
