Re: wuauclt.exe stealing CPU constantly. No access to Windows Upda

This could perhaps be a challenge for you guys (or girls for that matter) due
to my lack of good english... The problem is:

1)wuauclt.exe is running constantly using approx 50% CPU
2)Connection to Windows Update is very slow. After a while I get the error
code: 0x80248011.
3)Less important: Windows Defender is neither able to gain updates. I have
installed the latest version.

After the last attempt to use windows update, I have this from the logfile.
(Somewhat different from my first post...):

I am using Windows Update. Using "net stop wuaserv" does not stop the
wuauclt.exe process from running. Shouldnt it? Anyways; I have followed your
steps, after turning off Trend Micro Pc Cillin and Windows Defender (who
doesnt gain any updates either...). Under "step 2" I had to run the installer
manually because I got the message "...allready installed". After some time I
got installation failure with the code 0x8007041d....

Hi; i have tried several fixes and patches and whatever they are

The process wuauclt.exe runs constantly form startup and steals 50%
CPU. When I try to shut down the process it just restarts again.
Trying to shut down the process via cmd does not function either >

Although your description does not match the usual symptoms, it would be
worth upgrading to the latest versions of Windows Update, and then checking
for any symptoms remaining after that, in case the issue is now fixed.
Could you also confirm whether you are trying to use "Windows Update" or
"Microsoft Update", as stated in the heading of the update web page.

Before doing the items below, ensure that you have disabled all 3rd-party
anti-virus, anti-spyware, popup-blocker, download accelerator, or firewall.
If you disabled a 3rd-party firewall, then re-enable Windows Firewall for
the duration.

You might need to stop Automatic Updates while you apply these two fixes:
open a command prompt window and type the command:

net stop wuauserv

For a fix to the above problem, please do BOTH of the following:

1. (not for Vista) If your update history shows that you do not yet have
update KB927891 installed, then download and install update KB927891 ver3:
<http://support.microsoft.com/kb/927891>
and then restart Windows.

2. For 32-bit systems, download and save to hard disk, and then install:
<http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe>

If this produces an error message about "Update agent already
installed", then execute the installer again manually, with parameter
/wuforce as in (at a comand prompt window):

WindowsUpdateAgent30-x86.exe /wuforce

Then visit Microsoft Update again, and report back whether your problem is
fixed.
