80072ee2: why this error occurs?

Error 80072ee2 is common in all versions of Windows, starting from Windows 7/Windows Server 2008 R2 to Windows 10/Windows Server 2012 R2. This error can appear when you are installing updates via WSUS or when downloading updates from the Windows Update Center over the Internet.

Possible solutions for the Windows update error 80072ee2

Error code 80072ee2 according to the Windows Update error table on the MSFT site is interpreted as follows: ERROR_INTERNET_TIMEOUT (-2147012894) The request has timed out. This means that the system cannot access the Microsoft Update or WSUS sites.

Solution 2. Check Proxy and Firewall settings

Check if you are using a proxy server. If you do, double check the settings in the Internet Explorer and make sure that the proxy does not require a username or password to connect. If it does, the easiest way is to disable the proxy server during the duration of the windows update, although you can also create a workaround by setting your firewall to allow the connection to the Windows Update directly without going through the proxy.

If you are connecting to the Internet through a firewall, make sure that the following websites addresses are allowed in its settings:
HTTP: //* HTTPS: //*

Solution 3. Reset System Proxy Server Settings

If your computer has been infected with spyware in the past — or it is at the moment — then the spyware might have modified your Internet Explorer settings to use a proxy server. Open the cmd.exe utility (by typing CMD in the Start menu) and run the following command:

netsh winhttp import proxy source=ie

Solution 4. Re-register WU dlls

Some dll files might have become unregistered — due to a various factors — which could trigger the Windows update error 80072ee2. In this case, open elevated cmd.exe, and re-register some dlls by pasting the following lines:

regsvr32 oleaut32.dll
regsvr32 jscript.dll
regsvr32 vbscript.dll
regsvr32 softpub.dll
regsvr32 msxml.dll
regsvr32 wintrust.dll
regsvr32  initpki.dll
regsvr32 cryptdlg.dll

Wrong MTU setting can also cause 80072ee2 error. This is the rarest occurrence that may cause the 80072ee2, but your computer’s MTU setting might be incorrect. In this case, you simply have to set the MTU value to 1492 and try Windows Update again.

Solution 6. Fixing error 0x80072ee2 then updating via WSUS

If you receive Windows Updates from internal Windows Server Update Services (WSUS) server, open the Registry Editor (regedit.exe) and go to branch: HKEY_Local_Machine\Software\Policies\Microsoft\Windows\WindowsUpdate and check the WUServer and WUStatusServer. Verify that the correct WSUS server names are specified here.

80072ee2 registry

If you don’t want to use internal WSUS (but you want to receive updates directly from Windows Update), remove these parameters from the registry and restart the “Windows Update” service with the command:

net stop wuauserv && net start wuauserv

error 80072ee2 wuauserv

Solution 7. Lack of resources in the AppPool WSUS

If you are using WSUS server, perhaps the error is due to a lack of resources in the AppPool WSUS on a server. The solution is to remove the limit on the consumed memory.

Open IIS Manager Console -> Application Pools -> WsusPool -> Advanced Settings. Change Private Memory Limit to 0 and restart IIS.

Solution 8. Error 80072ee2 on a guest VM on Hyper-V

Sometimes when using Hyper-V, you may encounter a situation where Windows does not want to update inside the virtual machine (we ran into this on Windows Server 2008 R2). The system gives an error 80072EE2 and does not give any explanation. As it turned out, the error is related to the transmission parameter of large packets in the properties of the host network card. As a host, we have a physical server on which Hyper-V is deployed.

To solve the problem, run the Device Manager on the Hyper-V host and open the properties of the physical network card:

    [[[[[[The module “msxml.dll” failed to load.
    Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.

    Please help…

  • Curtis Van Dam

    I am not using a proxy and there is not one that was set up by spyware. verified through the command instructions in #2. It says failed to load program when i try to register the .dll files. And i am not sure how to change the setting of my computer’s MTU level. Please Help!

  • Harold

    I found another reason for the problem. The Win7 machine was pointing to an invalid WSUS server. Another website gave me the answer.

  • mary

    Thanks so much. The mtu fix worked for windows update. Now to get microsoft security essentials to update. I did system restore to factory fresh on an old laptop and couldn’t get updates. Hopefully windows update will fix whatever is broken with microsoft security essentials.

  • Asa Myth

    Many manufacturers distributed images with a policy set defining a automatic update server. The concise answer to this problem is to remove that registry key. The key is:


    remove this key, reboot, and windows updagte will work.

    • Thank you for commenting. Yes our Solution #5 points to an article which does exactly as you mention, removing the registry key.

    • macc

      There’s no WindowsUpdate folder for me

      • If there isn’t any WindowsUpdate folder than you probably don’t have a distributed image and so Solution #5 won’t work as a fix.

  • Thurman Merman

    #5 worked for me. I guess Dell has a WSUS server. Deleted the keys (and entries for Update servers in the WindowsUpdate key), restarted Windows Update service and away we went.

  • Maria Lowry

    I’m trying #3 but it says it doesn’t recognize that as a command, program, or batch file.

  • Maria Lowry

    I notice the “32” when trying to fix registry entries – does it matter that my windows 7 is 64 bit?

  • Eric Mosher

    Having this issue on a SBS 2011 box. Clients are no longer getting updated. Can’t update the server it self as well. Nothing seems to work. tried 1-4 and nothing worked. 5 didn’t apply as this was not installed by OEM. WSUS also doesn’t allow me to check the settings. It locks up every time. the only thing I can think of is that we used the wizard in SBS to move the data repository as it was on C and we were running out of disk space. So we moved it to D via the wizard. Any Idea?

  • Isaac Nogueira

    I’m having this same problem at Windows. it looks like the are blocked but the firewall is off.
    and I just can’t update from Win7 to Win10…

  • bitsian

    I tried the second step. For many, it was successful, others showed “The module was loaded but the call to DLLRegisterServer failed with error code 0x80004005”

  • Jamie Burrows

    I followed the steps provided, but non of them worked, i read somewhere else it could be something to do with the SBS firewall. Temp turned it off, and low and behold. Updating no problems. Added the window supdate websites by hand, turned it all back on and now no issues.

  • Andy

    I have this problem as well. I’ve tried all the solution windows recommends and also all the ones you have also. still doesn’t want to update. My notification flag says windows update can not update automaticly, but when I try manualyit still doesn’t work. So I figured I will just do my free windows 100 upgrade. Well guess what? It doesn’t work either. All that happens is a page opens that says windows 10 then closes real fast. Super bummed. Can you help?
    Thanks so much for your time,

  • Alex

    I fix it. Just go to HKLMSoftwarePoliciesMicrosoft WindowsWindowsUpdate and adjust the WSUS server settings (server name and IP address).

    On a freshly installed Windows Server 2008 R2 I have the following issue: I cannot download files from certain websites.
    For example
    – from the download runs perfectly
    – from the download starts but then it stops after a few secconds and some downloaded KB.
    This happens no matter of the browser; even installation kits or other software (including windows update) that are trying to download data from various internet locations are facing the same issue. All the other computers in the same network are working fine.
    I tried all the steps above (and some additional ones) but nothing worked. Last thing I tried was to set the MTU to 1430 according to this tutorial I used 1430 because pinging with packets of 1430 worked fine. After I rebooted the computer pinging with 1430 did not work anymore and I could not find a suitable value.
    Does anybody know what may be the issue?

  • Ed Brazell

    Thanks for the tutorial. It worked.
