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 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 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 that the following websites addresses are allowed in its settings:
- HTTP: //*.update.microsoft.com
- HTTPS: //*.update.microsoft.com
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 code 80072ee2
Go to the next solution if the previous command returned the following message:
Current WinHTTP proxy settings:
Direct access (no proxy server).

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 is left is to restart the Windows Update service using the following commands:

A wrong MTU setting can also cause 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 simply 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 branch HKEY_Local_Machine\Software\Policies\Microsoft\Windows\WindowsUpdate.
Check the WUServer and WUStatusServer names and make sure they are correct.
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, and 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 9. Error 80072ee2 on a Guest VM on Hyper-V
Sometimes, you may encounter the situation when while using a Hyper-V Windows does not want to update within the virtual machine (we ran into this on Windows Server 2008 R2). The system returns 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:
Go to the Advanced tab, find and disable two settings named Large Send Offload V2 (IPv4) and Large Send Offload V2 (IPv6). These settings are responsible for segmenting the network adapter of large data packets.
Save the changes and perform a new update search on the virtual machine.
Fix Error 80072ee2 Solution 10. Manual updates installation.
If you know which specific update you need to install but cannot due to Windows Update error 80072ee2, try installing them manually from Windows Update Catalog.
