Windows Update error 80072efd
I have CA Security Software firewall and the instruction for correcting this
update error says to add Windows update websites to a firewall exceptions
list. The problem is that in CA Security Firewall, it asks me to add to the
advanced application control list. I don't know what the name of the program
is. The website address looks nothing like the options coming up under the
application control list and when I select add, it asks me to select the file
to be added.
Re: Windows Update error 80072efd
The name of the product you posted is not specific.
These are *specific* names of CA products: CA Personal Firewall, CA
Internet Security Suite, etc.
The executables involved for Vista are wuauclt.exe and wuapp.exe.
RPC can *not* be blocked by the firewall, as shown here:
Some firewalls may reject network traffic that originates from Windows
Server 2003 Service Pack 1-based or Windows Vista-based computers

Suggest *not* doing any editing of the registry rather, visit CA's site
to learn how to allow RPC access.

Maybe you have a corrupted file.
This will probably not be your solution but it is easy and can't hurt to try.
Give this a try and see if it solves the problem................
Run SFC to see if any file from the OS has been delete or corrupt.
Go to Start > All Programs > Accessories and right-click
on the Command Prompt and choose "Run as administrator".
Type in: SFC /SCANNOW and press your Enter key.
Can you update Defender manually via

Look in the right side panel for a 32 bits

I'd suggest calling Microsoft: 1-866-pcsafety assuming U.S. or Canada. If
elsewhere, you can call the nearest number for paid Microsoft support and
ask for the free help for security patch or malware issues.
Re: Windows Update error 80072efd
I've been working on my friend's computer for a few hours trying to fix it up. He had viruses galore and I finally was able to delete them all. Then, his updates continued to fail. I tried all of Microsoft's suggestions as well as numerous other suggestions. None worked. I was close to giving up hope, but then tried what you said.
