Windows 7: Windows update error 80072EFE

18 Dec 2010   #1

Windows Home Premium 32 bit
Windows update error 80072EFE

I have just installed Windows 7 Home premium on 2 computers. A 64 bit version on my desktop and a 32 bit version on my laptop. Both computers are connected to the internet via the same router. The 64 bit desktop will update but the 32 bit laptop won't, I keep getting the 80072efe error.
After reading numerous topics about this error whereby internet connectivity is the most likely cause for this error, I don't think this is the case here as stated above obviously internet connectivity cannot be an issue as one is updating and the other is not....
The laptop is a Fujitsu S6510 and I have downloaded all the latest drivers from the Fujitsu web site.
Other things I have tried....
Added windows update to trusted sites in IE
Turned off firewall
Turned off antivirus (MSE)
Run TDS killer (no threats found)
Deleted Catroot2 folder from system32 folder
Installed the latest windows update agent

Has anyone else had a problem like this? Any help greatly appreciated...

Hello, and welcome to the Seven Forums!

The fact that one computer works, and the other doesn't, doesn't actually mean that it is not related to the internet connection. It just means that the error is probably not in the router. However, you have tried all of the common solutions already. What firewall are you using? Do you have two firewalls (you shouldn't). If nothing at all helps, try everything below, if nobody else has any ideas. I know there is a lot there, but you have already done all of the normal stuff:

EDIT: See bottom first

Please re-try Windows Update. This puts the error at the end of all the logs, and makes my job easier.

Please run the following tool in AGGRESSIVE mode: How do I reset Windows Update components?

Don't run it manually, that is just a waste of time. Aggressive mode will do what we need it to.

Now run this tool: Repair & Fix Windows Updates with Fix WU Utility | The Windows Club

Restart your computer and re-test Windows Update. If it works, do not continue.

If this has not solved your issue, I need to take some diagnostic logs to do some manual analysis.

NOTE to users reading this with the same problem. If the above has not cured your problem, you must run the below. However, the fixes for these diagnostic logs are different for every computer, even with the same error code. You MUST post these logs in your own thread, and not follow any user specific fixes I post to this user. Thanks!

This applied the same to Vista and 7. Do not worry that it says Vista: Please run steps 1, 2A, 3 (about 15 minutes), 4, 5 from this tutorial System Files - SFC Command Don't worry about the logs for the time being. I have a very good reason for not asking for them!

Download and run this tool: Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows 7, and for Windows Server 2008 R2 When it has finished installing the update, it is done!

When the above has completed, download and run FireGenUL: Altair Technologies Ltd. A console application will show on the screen for a few seconds.

Right, this has produces a log of logs for me. Please now upload them. To do this, create a new folder on your Desktop called LOGS. Navigate to C:\Windows\Logs and copy the entire CBS folder into your new LOGS folder. Navigate to C:\Windows\System32 and copy FireGenULReport.htm into your LOGS folder.

Close the LOGS folder, and right click on it > Send to > Compressed (zipped) folder. Upload that new zip file. Either upload it here, ideally, or if it is too big to Speedy Share - upload your files here or any other media sharing website.

Thanks, and good luck!


P.S. I know there is a lot here. Take care!
Just realised something you haven't tried yet. Start Orb > Control Panel > Internet Options > Connections tab > LAN Settings > uncheck any checkbox, to remove any proxy settings.

Then try the batch file at the end of this post (applies to 7 as well as Vista):

Good luck!

Windows 7 Ultimate (x64)

Greg, welcome to the Forums.

How is your laptop connected to the internet? Do you use wireless? If yes, have you tried plugging the ethernet cable in and use the wired (LAN) connection (I'm assuming your router connects to your desktop via the ethernet wire. It's posisble of course that you have a USB or wireless connection though). Do you have the same problem? If yes, can you connect your laptop to the internet at all?

Now, if you can confirm that your laptop is in fact connected to the internet, the IE can access websites, but the Windows update still does not work, try the Windows Update - Reset tutorial.
