Error 80072ee2 is common to all versions of Windows. This error can occur when installing updates via WSUS or when downloading updates from Windows Update Center on the Internet. The error code 80072ee2 according to the Windows Update error table on the MSFT side is interpreted as follows: ERROR_INTERNET_TIMEOUT (-2147012894) The request has expired. This means that the system cannot access the Microsoft Update or WSUS pages.
After installing a new Windows machine with the latest version of the Windows Update Agent, the software update check initiated by the Configuration Manager would fail with error 80072ee2 (which results in a connection delay).
Removing problematic Windows Update content and registry keys
The error can be caused by corrupted files and registry keys. If this is the case, you can delete the files and keys that cause problems. Incorrect deletion of registry keys can cause serious problems. Before doing this, it is recommended to backup the registry keys. Then, you can restore the deleted registry keys if necessary.
Then perform the following steps:
1. Press Win+R simultaneously (Windows logo key and R key). A Run dialog box opens.
2. enter services.msc in the execution field and click on the OK button.
3. search for the Windows Update service. Right-click and click Stop in the context menu.
4. Open C:\Windows\SoftwareDistribution and delete all content.
5. restart the Windows Update service. Right-click on the Windows Update Service and click Start.
6. Open the Run dialog box again. Type regedit in the execution field and click OK. Opens the registry editor.
7. In the Registry Editor, access HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate.
8. In the right-hand area, you see the WUServer and WUStatusServer keys. Right-click on each item and select Delete.
Check the proxy and firewall settings
Check if you are using a proxy server. In this case, check the settings in Internet Explorer and make sure that the proxy does not require a user name or password for login. If this is the case, the easiest way is to disable the proxy server for the duration of the Windows update, although you can also create a workaround by configuring your firewall to allow connection to Windows Update directly without using the proxy.
If you connect to the Internet through a firewall, make sure that the following website addresses are allowed in the settings:
HTTP: //*.update.microsoft.com HTTPS: //*.update.microsoft.com http://download.windowsupdate.com
Consult the official Microsoft documentation
In some cases, if you are using a Windows server, you should check the official Microsoft documentation and see if it applies to you. It seems that some updates have been replaced by other operating system updates.
This problem is quite common, which is why Windows has officially published documentation showing how to solve it. Review them and restart your computer completely after applying all the patches.
