Windows Update 80072ee2 Error Solution 3. Check Proxy and Firewall Settings
Check if you are using a proxy server. If you do, double-check the settings in Internet Explorer and make sure the proxy does not require a username or password to connect. If it does, the easiest way is to disable the proxy server for the period of checking, downloading, and applying Windows Updates. You can also apply a workaround by setting your firewall to allow the connection to the Windows Update directly without using the proxy.
If you are connecting to the Internet through a firewall, make sure the following website addresses are allowed in its settings:
- *windowsupdate.microsoft.com/*
- *update.microsoft.com/*
- *.windowsupdate.com/*
- *download.microsoft.com/*
- *test.stats.update.microsoft.com/*
- www.msftncsi.com/ncsi*
- *ntservicepack.microsoft.com/*
Check the availability of Windows Update nodes from your computer using the commands:
ping download.microsoft.com traceroute download.microsoft.com test-netconnection download.microsoft.com
If the hosts are not available, check your computer’s network settings (double-check if you are using dual NIC configuration), firewalls, and ISP connectivity.
If you can access the Internet from your local network only through a proxy server, you can check the system proxy settings as follows. List the current system proxy settings for WinHTTP:
netsh winhttp show proxy
Go to the next solution if the previous command returned the following message:
Current WinHTTP proxy settings:
Direct access (no proxy server).
Fixing Windows Update Error 80072ee2 Solution 4. Reset the Proxy Server Settings
The modified proxy server inside your browser may be a sign of spyware or malware intrusion. If you suspect this, make sure your antivirus software is up to date and running well.
If the netsh winhttp show proxy command returned the current proxy settings for WinHTTP and you see they are incorrect, reset them. To reset proxy server settings, launch the Command Prompt with Administrator privileges and enter the following commands:
netsh winhttp reset proxy netsh winhttp import proxy source=ie
You can also specify the proxy server settings manually. Do this only if you know the proxy server address and the connection port:
netsh winhttp set proxy proxy-server="192.168.1.11:3128" bypass-list="*.yourlocaldomain.com"
All that is left is to restart the Windows Update service using the following commands:
net stop wuauserv & net start wuauserv
Solve Error 80072ee2 Solution 5. Re-register Windows Update DLL Files
Some DLL (dynamically linked libraries) files might have become unregistered or corrupted due to various factors. This can cause the Windows update error 80072ee2. In this case, open the Command Prompt with Administrator privileges (also known as elevated) and re-register Windows Update DLL files 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
Now you need to stop the Windows Update service, clear its cache and launch it back so you can check whether what you did has fixed the 80072ee2 error or not. Here’s how to do that:
- Press Win + R on your keyboard and enter services.msc.
- Find the Windows Update service and stop it;
- Open the File Explorer, go to the C:\Windows\SoftwareDistribution folder, and delete everything inside;
- Go back to the Services window and start the Windows Update service.
Solution 6: Reset Windows Update Agent Setting
You can reset the current agent and Windows Update services settings using the ResetWUEng script. Download ResetWUEng.cmd from Github, and run it as Administrator.
Select the menu item 2 in the script that stands for Resets the Windows Update Components. After completing all the steps, restart the computer using item 17.
Solution 7: Change MTU Setting to 1492
A wrong MTU setting can also cause an 80072ee2 error. This is one of the rarest reasons why error 80072ee2 happens, but your computer’s MTU setting might be incorrect.
Check the current MTU value using the following command within the elevated Command Prompt:
netsh interface ipv4 show subinterfaces
In our case, the default MTU value for the main network LAN interface (Ethernet 0) is 1500. You can change the MTU value to 1492 using the next command:
netsh interface ipv4 set subinterface "Ethernet" mtu=1492 store=persistent
If another non-standard MTU value is used, you can reset it using the command:
netsh interface ipv4 reset
In this case, you need to set the MTU value to 1492, and try Windows Update again.
Solution 8. Fixing Error 0x80072ee2 Then Updating via WSUS
If you receive Windows Updates from the internal Windows Server Update Services (WSUS) server, open the Registry Editor (regedit.exe) and go to the registry key HKEY_Local_Machine\Software\Policies\Microsoft\Windows\WindowsUpdate.
Check the WUServer and WUStatusServer names and make sure they are correct. If not, enter a valid FQDN or IP address of your WSUS server.
If you do not want to use the internal WSUS (but you want to receive updates directly from Windows Update), remove these parameters from the registry. Then restart the “Windows Update” service with the following command:
net stop wuauserv && net start wuauserv
Solution 8. Lack of Resources in the AppPool WSUS
If you are using the WSUS server to distribute Windows Update to your clients, perhaps the error is due to a lack of resources in the WSUS IIS AppPool 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 and restart IIS.
Solution 10: Update Windows 7/2008R2 Devices to Support SHA-2 Endpoints
You may encounter the error 80072ee2 if you try to check for updates after September 2019 on a clean installed Windows 7 SP1, Windows Server 2008 R2 Service Pack 1, or Windows Server 2008 SP2. The RTM versions of these OSs use the SHA-1 hashing algorithm to connect to the Windows Update service endpoint. Since September 2019, Microsoft has completely discontinued SHA-1 based endpoints for older Windows devices.
Due to several shortcomings of the SHA-1 algorithm and the need to comply with modern industry standards, Microsoft began to sign Windows updates exclusively using the more secure SHA-2 algorithm.
If you are trying to connect to Windows Update from older versions of Windows, you will receive an error:
Error code 80072ee2: The device cannot connect to Windows Update.
Your older Windows devices can continue to use Windows Update by manually installing certain updates that allow you to connect to the SHA-2 service endpoints.
Hint. In all modern Windows versions starting from Windows 8 and Windows Server 2012, all the connections to Windows Update service endpoints are established using the more modern algorithm (SHA-256).
To continue using Windows Update for your older Windows devices, you need to download and install the following two specific updates:
Update 1: SHA-2 Code Signing Support
This update will allow your device to verify updates signatures by using more secure SHA-2 hashing algorithms:
- KB4474419 — SHA-2 code signing support update (Windows 7 SP1, Windows Server 2008 R2 SP1);
- KB4484071 — SHA2 support for your WSUS server running Windows Server Update Services 3.0 SP1 or 3.2. The only case when you need to install this update is if you are using this WSUS version to deploy update on Windows device in your corporate network.
Update 2: SHA-2 Related Servicing Stack Updates
Apply this update in order the Windows Update servicing stack could validate SHA-2 signatures and direct affected Windows devices to communicate with the SHA-2 based service endpoints of Windows Update.
- KB4490628 — Servicing stack update for Windows 7 SP1 and Windows Server 2008 R2 SP1;
- KB4493730 — WU Service Stack Updates for Windows Server 2008 SP2.
These updates must be manually installed immediately after installing Windows. After that, the wuauserv service will start receiving updates from Windows Update or WSUS as usual.
Fix Error 80072ee2 Solution 11. Manual Updates Installation
If you know which specific update you need to install but you cannot due to Windows Update error 80072ee2, try installing them manually from Windows Update Catalog. All you need to know is which Windows version you have (for example, Windows 10 21H2 Professional x64) and the update codename (for example, KB5014699, according to https://support.microsoft.com/en-us/topic/windows-10-update-history-857b8ccb-71e4-49e5-b3f6-7073197d98fb).
Go to the Windows Update Catalog website and enter the update code in the search field. Locate the update you need and make sure it is the one for your system. Here is how to interpret the name of each update. For example, here’s the update name:
2022-06 Cumulative Update for Windows 10 Version 21H2 for x64-based Systems (KB5014699)
It means you have an update for June 2022 for computers with Windows 10 version 1903 and later with x64-based processors.
Download the update manually and launch the .msu file. Wait for the system to install the update and then restart your computer.
Windows update process is a risky task having dual nature because the process triggers problems on plenty of occasions but when you are successful to install it adds important improvements. While trying to upgrade your current Windows version, error 80072ee2 may arise during the downloading process or after a certain portion has been downloaded. The code mostly appears when the System searches for updates automatically via Windows Update. A stable internet connection is fundamental when you try to update Windows through WSUS or from the update center, thus, a poor network can be the culprit. This could be the reason why the system fails to establish a connection to the server and ends up with update error 80072ee2.

Сброс настроек системного прокси
Проверьте, не изменились ли у вас настройки системного прокси-сервера (это часто делают различные вирусы и трояны). Для этого, откройте командную строку с правами администратора и выполните команду, импортирующую настройки системного прокси-сервера из параметров IE.
netsh winhttp import proxy source=ie
Перерегистрация библиотек агента обновления Windows
В некоторых случаях отсутствие регистрации динамических библиотек службы обновления Windows также может вызывать ошибку 80072ee2. В этом случае рекомендуется в командной строке (с правами администратора) перерегистрировать все связанные с службой Windows Update dll-библиотеки):
regsvr32 oleaut32.dll
regsvr32 jscript.dll
regsvr32 vbscript.dll
regsvr32 softpub.dll
regsvr32 msxml.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 cryptdlg.dll
Изменение размера MTU на 1492
Установка некорректного размера MTU также может приводить к появлению ошибки 80072ee2 (конечно, это не самый распространенная причина, но отметать ее не стоит). Проверьте текущий размер MTU командой
netsh interface ipv4 show subinterfaces
Для изменения размера MTU на значение 1452 для проводного интерфейса используется команда
netsh interface ipv4 set subinterface "Local Area Connection" mtu=1452 store=persistent
а для беспроводного интерфейса:
netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1452 store=persistent
Исправлении ошибки 0x80072ee2 при установке обновлений через WSUS
Если данная ошибка обновления Windows появляется при установке обновления с внутреннего сервера WSUS, рекомендуется проверить корректность его настройки в реестре. Запустите regedit.exe, перейдите к следующему разделу реестра: HKEY_Local_Machine\Software\Policies\Microsoft\Windows\WindowsUpdate и проверьте значение в параметров WUServer и WUStatusServer. Они должны указывать на действующий адрес вашего WSUS сервера.
Если вы не хотите использовать внутренний WSUS, а хотите получать обновления непосредственно из Центра обновления Windows, удалите эти параметры из реестра и перезапустите службу «Windows Update» командой:
net stop wuauserv && net start wuauserv
Недостаток ресурсов для пула WsusPool
В том случае, если для распространения обновлений вы используете собственный сервер WSUS, проверьте нет ли проблем с доступными ресурсами на сервере. При недостатке памяти пул IIS, отвечающий за работу WSUS сервера может периодически отваливаться (WsusPool). Попробуйте убрать ограничение на использование оперативной памяти для пула WsusPool. Откройте консоль IIS Manager и перейдите в раздел Application Pools-> WsusPool->Advanced Settings. Измените значение параметра Private Memory Limit на 0 и перезапустите IIS.
Ошибка 0x80072ee2 в виртуальных машинах Hyper-V
При использовании среды виртуализации Hyper-V иногда может возникнуть ситуация, когда Windows в гостевых виртуальных машинах не может обновляться. Я несколько раз сталкивался с этим на Windows Server 2008 R2. Система выдает ошибку 80072EE2 и все тут. Как оказалось, ошибка связана с параметром физического сетевого адаптера сервера Hyper-V, отвечающего за передачу больших пакетов.
Чтобы исправить проблему, нужно на хостовом гипервизоре Hyper-V запустить диспетчер устройств и открыть свойства физического сетевого адаптера.
На вкладке Advanced нужно отключить следующие параметры: Large Send Offload V2 (IPv4) и Large Send Offload V2 (IPv6). Эти параметры отвечают за сегментирование больших пакетов данных драйвером сетевого адаптера.

Every once in a while you might run into an issue with a Windows server not receiving windows updates from WSUS. There are so many reasons why Windows Updates are not working on a server, this article resolves one such error code. The steps below were used to resolve the following Windows Update error: Code 80072EE2 Windows Update encountered and unknown error
Windows could not search for new updates
Code 80072EE2
1. Check the status of the server in question in WSUS. Make sure the server is communicating. In one particular example, the server in question had the wrong IP address assigned in WSUS. Delete the server from the WSUS database.
2. From the server in question, open a command line as Administrator and run wuauclt /resetauthorization. Wait a few minutes and then run wuauclt /detectnow. You can also choose to restart the Windows Update service.
3. Open the C:\Windows\WindowsUpdate.log file and monitor it. If you receive the same error, continue with the steps below.
4. From the server in question, open a command line as Administrator and run netsh winhttp show. This will display the HTTP proxy settings for the server.
5. Notice in the example above, there is a proxy server setting configured. In our case, we don’t want a proxy server. The WU process is trying to go through the proxy server at http://10.1.10.99:8080 and it is not able to. This is most likely the reason for the windows update failure.
6. From the server in question, open a command line as Administrator and run netsh winhttp reset proxy. This will clear the proxy server information. Notice now it states “Direct access (no proxy server)”.
7. From the server in question, open a command line as Administrator and run wuauclt /resetauthorization (it may not be necessary but it won’t hurt). Wait a few minutes and then run wuauclt /detectnow. You can also choose to restart the Windows Update service.
8. Open the C:\Windows\WindowsUpdate.log file and monitor it. If you receive the same error, continue with the steps below.
After a little while, the server should successfully communicate to the WSUS server and the windows updates should start downloading.
