Windows Update Error 80072EE2


I am running a 64-bit version of Windows 7 Home Basic. I am trying to update the Windows but the update fails with an error code 80072EE2. I am connected to the internet through proxy.

Here are some things listed in my WindowsUpdate.log:

Access type: No proxy
WSUS server: <NULL>
WSUS status server: <NULL>

Then the download manager is restoring some persisted download calls. Then,

Initializing Automatic Updates
WARNING: SendRequest failed with hr = 80072ee7. Proxy List used: <(null)> Bypass List used : <(null)> Auth Schemes used : <>
UpdateDownloadProperties: download priority has changed from 1 to 2.
WARNING: Failed to change download properties of call, error = 0x80070057
WARNING: WinHttp: SendRequestToServerForFileInformation MakeRequest failed. error 0x8024402c
WARNING: WinHttp: SendRequestToServerForFileInformation failed with 0x8024402c
WARNING: WinHttp: ShouldFileBeDownloaded failed with 0x8024402c
Error 0x8024402c occurred while downloading update; notifying dependent calls.

There are very many errors/warnings and some other things listed in the log file. I have copied above the ones I thought are relevant to my problem.

Note that I have tried the solution provided on the Microsoft website but that was unable to solve my problem.

Can someone help me resolve this error?

Solution 1

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.

Solution 2

If your computer has been infested 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 program (by typing CMD in the start menu) and issue the following command: netsh winhttp import proxy source=ie

Solution 3

Some dll files might have become unregistered – due to various factors – which could trigger the windows update error 80072ee2. In this case, open cmd.exe, and register the following dlls: oleaut32.dll, jscript.dll, vbscript.dll, msxml.dll, softpub.dll, wintrust.dll, initpki.dll, cryptdlg.dll. You can register a dll by typing regsvr32 {name of the dll}.

Solution 4

This is the rarest occurrence that may cause the windows update error 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 the windows update again.

Solution 5

Also, please check this solution as well. It has to do with Windows Updates being set to receive them via WSUS.

These are all possible solutions to the windows update error 80072ee2. In case you still can not fix the error, leave a comment below and we will assist you.
