Windows update error 80072EE2 is a common problem that occurs when you try to check for updates on your Windows 7 computer.
This error can be caused by various reasons, such as corrupted files, registry keys, firewall settings, or internet connection issues.
I have both the 32-bit version and 64-bit version of Windows 7 and I recently logged into the 64-bit version, only to find out that windows update error code 80072ee2 is occurring.
Not only Windows 7 update feature failed to work, but web pages were also not opening in Internet Explorer, Mozilla Firefox and Google Chrome, though internet connection was working.
I was little stunned at first, as the these things were properly working on my 32-bit version.

How I Fixed Windows 7 update problem
So I tried to do a little research on Google and found the reason.
The Windows 7 64-bit version security features are still tough to understand and found that you need to include these browsers in the exceptions to Windows 7 firewall entries.
Though this solved my problem of web pages not opening in my favourite browsers, the original problem of windows 7 64-bit update not working, still remained.

Simple Solutions to 80072ee2 error
Fix #1 : Uninstall Unused Network Adapters
You can have 2 Network adapters, with one working and another not-working.
In my case, the Atheros (non-working) Network adapter created another Local Area connection which was disabled.
So I uninstalled this network adapter and the Windows 7 64 bit update started working fine. You can achieve this by these simple steps.
Right click the ‘My computer’ icon on the desktop
Select ‘Properties’ > ‘Hardware’ tab > ‘Device Manager’
Select ‘Network Adapters’ by clicking the ‘+’ sign
Right click the adapter connecting the pc to the home lan or gateway router
Windows 7 will find the drivers again and reload them.
If you have a non-working or useless network adapter like me, check also “Delete the driver software for this device” after you do uninstall, which will completely remove that particular driver software.
Fix #2 : Remove the Ethernet Device
@Gregd on techarena.in had a similar problem related to 80072EE2.
I have a pc which uses ICS to connect all the clients in my home network to the internet. WU would not work on either client. Kept getting 80072ee2 failure when searching for updates. Tried every solution I could find on the internet.
Finally I added up all the symptoms, one of which that I could not load other https pages, could not even reach the windows update site without using the proxy. Well, I decided the problem could be the ethernet connection from the ICS Host to the home network.
Removed the ethernet device from within device manager, rebooted and let XP home reinstall the device. After that, the clients could run Windows Update.
Fix #3 : Uninstall VMware or Virtual Nics
@Damien faced a similar problem, but related to physical nic and two virtual nics.
I had the same problem and when I read your post I thought that some conflict exits on my nic. But apart from my physical nic I have two more virtual nics due to VMware installation. So I unistalled VMware and update worked!!
I just resolved mine too … make sure ur Antivirus does not block any Bonjour Service … My McAfee blocked that service … so I unblocked it before the problem was solved.
Fix #4 : Shut Down HyperVisor VMs
@brainiac faced problems with his Hypervisor virtual machines.
My Windows Update suddenly stopped working several weeks ago. I run Windows Server 2008 with two virtual machines in Hypervisor. This system was set up a half year ago, then suddenly Windows Update started erroring with 80072ee2 (ERROR_WINHTTP_TIMEOUT) and 80072f78 (ERROR_WINHTTP_INVALID_SERVER_RESPONSE).
With this post and mention of VMWare, I finally fixed my version of the problem: simply shutting down the Hypervisor VMs and letting Windows Update run without the VMs stealing bandwidth.
Fix #5 : Uninstall Multi AntiVirus Programs
There may be some other issues like internet connectivity, third-party firewalls, third-party antivirus software, software accelerator programs, windows updated sites not added to trusted sites list etc which may cause this Code 80072EE2 error.
The solution to such problems is in this Microsoft knowledge base article – KB 836941
Fix #6 : Add Firewall Exceptions
Sometimes it may be firewall exceptions list, where you need to add the following code to your firewall’s exceptions or “allow” list.
Windows Firewall ships with this version of Windows and should already include these sites in the exceptions list. If you use a different firewall, refer to the software publisher’s help to see how to add these websites to your firewall exceptions list:
So, these are some of the solutions to the Windows 7 Update not working problem with Code 80072EE2 Error.
