1. Have you used elevated rights when registered dll? I mean "Run as Administrator".

2. Is there any "forensic" info in windowsupdate log file?

3. Have you run Windows Readiness Tool yet? http://support.microsoft.com/kb/947821/en-us

4. I does not hurt if you test system with  sfc /scannow

Regards

Hi,

I notice Background Intelligent Transfer Service (BITS) doesn't exist as well. I suspect the computer is infected by virus. Please use your security software to scan the computer in Safe Mode first. Meanwhile, please check if the following registries are available.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BITS

If these two registries doesn't exist, you may need to export them from the health computer and then import them on your problematic computer.

Go to Start / All Programs / Accessories. Right Click the 'Command Prompt' item and click the 'Run As Administrator' option. In the Command Prompt window, Paste the following command.

REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BITS

where i  can get them?

After copying the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv registry entries from a working computer and running REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL, everything is working again!

Thank you!!!!

We used the below

We also copied the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv registry entries from a working computer and run REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL

The service was back, however we still got an error message which we had also recenlty resolved on another PC and that was a corrupt software distribution repositry. So we ran the following command.

• Net stop wuauserv

• cd %systemroot%
• Ren SoftwareDistribution SoftwareDistribution.old
• Net start wuauserv

Started the Windows update service and checked that Windows update was working.

And just when I thought it was all over, once it had gone and gathered the list of updates to download it decided to fail. BITS was also missing, I'd missed it entirely, had to run the following command to re-create the service and the start it up.

sc create BITS binpath= "c:\windows\system32\svchost.exe -k netsvcs" start= delayed-auto

Now it seems to be working.

Hi,

My issue resolved With "REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL".

 "REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL".

Worked, I seriously doubt the system has been infected, I actually have MSE running all the time and updated, the windows update service just disappear without any error report until today I try to check the update manually.

Hi

I am not a techie, and am trying to work out how to install windows updater when the registry file is missing.  I do not have another computer or laptop to copy the hotkey file into my laptop.

I removed a malware - well Norton did - a couple of days ago, and expected the Windows 7 uodater to work.  But it failed, with the known message - service is missing.

Can anyone advise? Is there something I can download from Microsoft to help me?

Thanks

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BITS but I dont have bits and windows update in service list

BY DOING THIS FOLLOWING MESSAGE APPEARS

The module "C:\Windows\SYSTEM32\WUAUENG.DLL" was loaded but the call to DllResisterServer Failed with error code 0x80070005.
