How To Fix Windows Update Error 0x80070424

When you run the Windows Update service, you may sometimes discover that you are not able to install any windows updates or even use the windows update website. Instead, you get a message like:

The website has encountered a problem and cannot display the page you are trying to view. The options provided below might help you solve the problem

Then there is an error code 0x80070424. It could also show up as error 80070424.

This could be a symptom of one or more of the following problems:

  • The Automatic Updates feature is turned off in Security Center and you cannot turn this feature on.
  • The Automatic Updates service is missing from the Services snap-in.
  • The registry is missing one or both of the following registry subkeys:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceswuauserv
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumRootLEGACY_WUAUSERV

What this simply means is that Windows thinks the update service does not exist on your computer either because it was accidentally de-registered or was not installed properly. So you get error 0x80070424.

The fastest way to fix Windows Update Error 0x80070424 is to re-register the Windows Update and Automatic Update services by running the following commands either using command prompt or the “Run” option.

Option 1:

  • Go to Start>Run
  • Type regsvr32 wuaueng.dll
  • Click on OK wait a few seconds, then click on OK in the RegSvr32 dialog box.
  • Click on Start>Run key in regedit then click on OK
    Navigate to:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceswuauserv
    Look for a DeleteFlag value and, if it exists, right-click on it and select
    Delete.

Option 2:

Open the command prompt, or the “Run” box and type, or cut and paste the following:

%systemroot%system32regsvr32.exe %systemroot%system32wuaneng.dll

This will register the Windows Update service and a dialog box should display to say the commands were executed successfully. You can then retry the Windows Update service again.

It may also help to make sure that required Windows Update services like the Background Intelligent Transfer Service, Windows Update and Workstation services are running. If they are not, start those services.

To check and start required Windows Update services:

  • Click on Start, select “Run” and type in “Services.msc“. You may be prompted for an administrator password or confirmation.
  • In the Services dialog box, click Background Intelligent Transfer Service
  • Note the status of the selection. If it shows Stopped, right-click the service and click “Start”.

Do the same for Windows Update and the Workstation services.

In some weird instances, when you look in the “Services” section under Administrative tools, the Windows Update service may not appear at all. If that is the case, see this article about installing the Windows Update agent.

Additionally, Microsoft has also made version 7.4.7600.226 of the Windows Update Agent available and you can get the files here.

You must know which kind of processor platform (x86-based, x64-based, or Itanium-based) that you have. Most users have x86-based processors [http://support.microsoft.com/kb/949104]

To learn which version of Windows that you are running, or to learn whether it is a 32-bit version or 64-bit version, open System Information (Msinfo32.exe). Then, review the value that is listed for System Type. To do this, follow these steps:

Step 1:
Click Start, and then click Run, or click Start Search.
Type msinfo32.exe, and then press ENTER.
In System Information, review the value for System Type.
For 32-bit editions of Windows, the System Type value is x86-based PC.
For 64-bit editions of Windows, the System Type value is x64-based PC.

Step 2:
Download Windows Update Agent for Windows Vista, Windows Server 2008, Windows XP, Windows Server 2003, and Windows 2000 Service Pack 4
