Windows Update error 80072EE2
Solution 1
In case you are not getting updates directly from Microsoft but for a WSUS server.
- Open the registry editor : regedit
- Go to HKLM/SOFTWARE/Policies/Microsoft/Windows/WindowsUpdate
- Check the following values and correct them if necessary
WUServer
WUStatusServer
Solution 2
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 3
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 4
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:
regsvr32 oleaut32.dll
regsvr32 jscript.dll
regsvr32 vbscript.dll
regsvr32 msxml.dll
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 cryptdlg.dll.
Solution 5
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 6
- Open RegEdit and navigate to HKLM\Software\Policies\Microsoft\ Windows\WindowsUpdate
- Remove any and all values within this key. Most likely, the culprit is a faulty Windows Update source server. Sometimes this is the result of a latent or previous infection.
- Finally, download and run Microsoft FixIt 50202. Try the Default settings first, and if that does not work, try Aggressive.
- Reboot the computer and check to see that Windows Update is working properly.
