Fix WinOS Update 80072efd Error

Overview - What is WinOS Update Error 80072efd?

WinOS update error 80072efd is related specifically to downloading and installing WinOS updates from Microsoft's servers and indicates there is an issue gaining a connection.

It is common to see this error message if Microsoft's servers are overloaded with update requests. It can also be seen if third party firewall software or proxy services are interfering with the Internet connection.

Common causes for Seeing WinOS Update Error 80072efd

The main cause for receiving an 80072efd error is due to your computer being unable to communicate with Microsoft's update servers. This could either be because they are down and unavailable or unavailable due to high demand.

You could also have trouble connecting to Microsoft's update servers if you are using a third party firewall that is blocking the relevant update ports. A badly configured proxy server can also contribute to receiving this error when your computer attempts to contact Microsoft.

In some cases, infection by a virus or malicious software can interfere with the WinOS Update process. If this is the case, you may receive a WinOS Update Error 80072efd.

Solutions - How to Solve WinOS Update Error 80072efd

Busy Servers - If it's the first time you've seen this error, it could be that Microsoft's servers are just busy and unavailable. In this case, simply close WinOS Update and try again later. Usually server downtime will last no longer than 10 to 15 minutes. The most likely outcome is the update will succeed at a later time.

Firewalls and Proxy Servers - If this error message persists, you may be inadvertently blocking the update process by the use of a firewall or proxy server. Turning off these programs can temporarily verify if this is the case.

If the update succeeded with your firewall turned off, you may need to add exceptions to your firewall so WinOS Update can operate unhindered in the future. This is particularly true of third party firewalls, as the built in WinOS firewall generally has these exceptions already entered by default.

Add the following URLs to your firewall's white list:

Once these URLs are added, retry the WinOS update with your firewall turned on.

Viruses and Malicious Software - Run a complete system scan with your anti-virus and anti-malware software. Repair any issues it may find, and then try the WinOS update again.

Advanced Troubleshooting for WinOS Update Errors

If you are still experiencing difficulty with WinOS Update Errors, then you can try one of the following:

  • Disable all firewalls, anti-malware and anti-virus software temporarily whilst running WinOS Update.
  • Disable any software accelerator programs
  • Make sure you have the latest updates installed for Background Intelligent Transfer Service.

If you are attempting to troubleshoot this problem whilst your anti-virus and anti-malware software is switched off, it's suggested that you only access safe and trusted websites, do not use instant messenger services and do not open emails or attachments.
