Check for Windows Update on Windows 10 (technical preview)
Error code 80072EFD basically means there is some kind of connectivity issue between your machine and Windows Update. The error code existed in previous versions of Windows (7 and 8 at least) and the method to diagnose the fault is the same.
Ensure you're not using a firewall that is blocking connections to the following addresses:
- http://*.update.microsoft.com
- https://*.update.microsoft.com
- http://download.windowsupdate.com
Alternatively, ensure that the Windows Update service can make outgoing connections on ports 80 and 443.
The default Windows firewall should already allow connections to these addresses but it's worth checking anyway.
Also ensure that the Background Intelligent Transfer Service (BITS) is running as this is required for Windows Update to function correctly.
Failing that, here are some Microsoft resources that may help:
- Temporary connection-related errors may occur when you use Windows Update
- How do I reset Windows Update components

I'am not able to check for Updates on Windows 10 Techpreview. Everytime I try I get error: 80072EFD I try some workarounds but nothing works.
- Update works on Windows defender
- Check Date and Time
- Check internet connection
- disable Firewall
Without update service I'am not able to install Features like (.Net 3.5) anybody knows to solve this issue. It is a temporary problem on Windows update Servers?

Ramhound over 9 years.NET 3.5 is added through Add/Remove not Windows Update. Most of the time when one encounters this error it means the installation is corrupt.

Iszi over 9 yearsHaving the same problem on some Surface 3s today (Win 8 Pro) too. Some are fresh out of the box. Some have gone through OS reloads for good measure to troubleshoot. Problem exists on multiple devices, using different networks. Tried Windows Update troubleshooter & Internet Connection troubleshooter. No dice.

kockiren over 9 years@magicandre1981: Yes I know it is a Internet issue but the Internetconnection works. Updates on defender works for example and all other traffic too. Only the Update won't works
