Installing Windows Update client error 0x8007041d

When installing the latest version of the Windows Update Client, you may recieve an error that references this code: 0x8007041d

0x8007041d simply refers to not being able to stop, restart or manipulate in some way, the Windows Update service.

With a recent version of the Windows Update agent installed, the C:windowsWindowsUpdate.log file will produce and error similair to the following:

This can occur with the Standalone Installer, as in the example above, but also when updating your Windows Update client though the Windows Update homepage.

On the web you will find references to Norton virusscanner possibly causing this, but its not the only reason this can happen. ( ) In fact there are any number of reasons a Windows server can fail to unload.

The Windows Update service is launched by the system, under system account credentials, and with the following command line: C:windowssystem32svchost.exe -k wugroup

If the service is trapped in the “stopping” state, you may wanna kill the process manually, however, you can only do this on a Windows 2000 machine! As I will show below…

But because the service is launced via cvchost, you might have a hard time recognising which instance of cvchost to kill.


Process Explorer has an option to show the command line with which all system processes have been started. This is simply a column you have to turn on in the main view.


The Windows XP / W2K3 command tasklist.exe will give you much the same data:

On a Windows 2000 Server:

A funny thing to note here is the difference between Windows 2000 and Windows XP / W2K3. On Windows 2000 Server, the wuauserv service is run as a completely seperate process, with its own ID.
This means you can kill it seperatly.

But on Windows XP / W2K3, it is launched as part of the Network Services group. This is reflected in the command line in which it is launched:
C:WINDOWSsystem32svchost.exe -k netsvcs

You cant simply kill svchost.exe in this case, it will crash the system.
Recommended is to disable the service, reboot, and after reboot install the standalone Windows Update Agent.


  1. We had this issue a Windows Server 2003 64bit and deleting the follow registry value solved it:
    WOW64=0x1 <– Delete this

  2. Deleting HKLM\SYSTEM\CurrentControlSet\Services\wuauserv
    WOW64=0×1 did the trick for me too. Who’d thunk it? 🙁
