Windows 7: Windows Update Error 80072EE2

I'm using Avira Premium Security Suite and I have no problem updating.

BTW, have you activated Windows yet?

I don't know which version you have (32 or 64 bit) so here's instrctions for both.

For 32-bit Windows, open a command prompt (run as Administrator) and enter the following lines:

net stop wuauserv
regsvr32 %windir%\system32\wups2.dll
net start wuauserv


For 64-bit Windows, the second line differs due to the location of the DLL file:

net stop wuauserv
regsvr32 %windir%\syswow64\wups2.dll
net start wuauserv


In each case, the first and last commands stop and then restart the Windows Update service. This is a precaution to keep the service from becoming unstable.
on a 32-bit system,a single short command regsvr32 wups2.dll solved the problem without confusing the WU/AU service.

Hey Lumpy,

It looks like we both have the same problem. I too have tried all the methods posted here and other forums but no luck. Anyone to help us out?

Here's a question - if you run a wireshark capture whilst attempting to contact Windows Update, and then save the resulting session out to a .cap file, can you upload it here? Make a note of your client IP address, and we can see if we see the problem on the wire. Also, does your network require a proxy configured in your browser to get to the internet, or no?

  1. Install Wireshark
  2. Open Wireshark, and click Capture > Interfaces
  3. Click the "Start" button next to your network adapter
  4. Open Windows Update and reproduce the error
  5. Go back to the Wireshark window, and click Capture > Stop
  6. Click File > Save As..., give the file a name in the "File name" box, and then click the "Save" button.
That will create a file with the name you specified with a .cap file extension, that you can zip or rar up and then upload somewhere for us to download and analyze.

The problem is that when you request from DNS the address of www.update.microsoft.com, your DNS server at 192.168.1.1 (probably your router?) is returning 72.14.205.100, which is *not* the correct address of www.update.microsoft.com. This causes your system to send a SYN packet to 72.14.205.100 to try and set up a TCP connection, but because that host does not respond (it is actually an IP address registered to Google), you never get to Windows Update (the error WU is giving you is correct - this is timing out). The error is with your router, or with the upstream DNS server your router is using to get it's addresses. If rebooting your router doesn't fix it, contact whomever is your DNS provider (perhaps your ISP?) to get this fixed, or configure your router to use different DNS servers on a different service (like OpenDNS). Something is sending you to Google (and it appears this machine does not respond to TCP requests) instead of Microsoft for that DNS name, which is causing the failure. Check your router, and go from there - the problem is not WU, or even anything on your system. It's your router, or the DNS servers that you have configured your router to use.
