Windows Update Error Code 80072EFD


This is a relatively fresh install a couple months back I never updated then when I decided to I think it was two months ago, it just suddenly kept giving me this. Funny because it seems everytime I try and update windows **** like this happens and their a product of their own failure.

Anyways I ran the loop:
sfc /scannow, no dice
mal-ware antimalware bytes, no dice
firewall is never enabled, no dice
no anti-virus since they are viruses anyways but ran AVG and avast temporarily, no dice.
Searched the web kept finding solutions for Vista.

Specs are:

Windows 7 Ultimate SP1, 0 updates.

I had the same issue last week and could not repair the fault , i found a repair tool at DLL ERROR REPAIR which checked all system files and repaired the currupted file.

Hope that helps

Problem: When you try to use Windows Update or update Windows Defender to check for and install updates, you receive one of the following error messages:

Windows Defender error code 0x80072efd
Windows Update error code 80072efd

The following solution worked for me on a PC running Vista SP1. This was after all of the other suggestions provided by Microsoft Support at Temporary connection-related errors may occur when you use Windows Update or Microsoft Update and How do I reset Windows Update components? did not work.

Solution (Vista SP 1):

1. Click the "Start" Button, click "All programs", and click "Accessories".

2. Right-click “Command Prompt” Run as administrator". If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Type "netsh winhttp reset proxy" (without quotes) at the command prompt, and press Enter.

4. Try the update again.

Well, I believe your problem is kinda related with corrupt OS files, incorrect system settings and so on. What you have to do is simply check system files for corruption, restore your machine to an earlier date. Use a hotfix available and if doesn't work go with the other options.
