Windows Update fails with code 8024402C

Question

Windows Update keeps failing with code 8024402C, on two separate Windows 7 Home Premium machines. I've looked through loads of similar questions here but none of the answers resolves the problem.

If I try the Microsoft Fixit, that fails with a code of 80072EE7

If I try any manual download of updates or tools from either machine, my browser tells me that it can't find download.microsoft.com.

I've gone through the whole of kb2509997. In most cases the suggested methods didn't work. In the remainder, there was a problem following it:

running checksur.exe didn't work

running sfc /scannow didn't work

Resetting the contents of the catroot2 folder didn't work

Checking for incorrect registry values didn't work (the subkey to search didn't exist!)

Registering the Windows Update files didn't work

My antivirus software (Bullguard 10) doesn't scan the SoftwareDistribution folder

Renaming the SoftwareDistribution folder didn't work

Clearing the BITS queue didn't work

I couldn't find a KB958056 update

I couldn't find a pending.xml - the c:\windows\winsxs folder that it's supposed to be in doesn't exist.

Running chkdsk didn't work

The fact that it doesn't seem to be able to find download.microsoft.com suggests to me that it's a DNS problem. But another machine running XP Professional (luckily!) doesn't encounter the same problems. This is connecting through the same broadband router and has the same firewall and antivirus software (Bullguard) so it can't be a firewall issue, either at the Bullguard level or at the router level.

Thanks in advance for any advice.

Hi,

Thank you for keeping us posted.

I can understand the inconvenience caused to you. You may follow these methods and check if that helps you in fixing the issue:

Method 1: You can run the windows update troubleshooter and check if it helps:

Open the Windows Update troubleshooter

**http://windows.microsoft.com/en-US/windows7/Open-the-Windows-Update-troubleshooter**

---

Method 2: You may run the System Update Readiness Tool and check if that works. 

a.       You will first need to download the utility.

System Update Readiness Tool for Windows 7 (32 bits)

http://www.microsoft.com/downloads/en/details.aspx?FamilyID=44e15787-66b0-4e9c-9c3b-1fc9ea40f69f

System Update Readiness Tool for Windows 7 (64 bits)

http://www.microsoft.com/downloads/en/details.aspx?FamilyID=914fbc5b-1fba-4bae-a7c3-d2c47c6fcffc

b.      Click Download, and then Open when prompted.

c.       Once the download completes click OK on the Windows Update Standalone Installer notification.

d.      You will see The updates are being installed with a progress bar – do not cancel this process.

e.      You will receive an onscreen notification saying that the update has been successfully installed.

f.        The results of this tool are output to a log file stored on your computer which you will need to retrieve.

g.       Please click Start, click Computer, click Local Disk (C:) or whichever drive Windows is installed to.

h.      Then click on the Windows folder, click on the Logs folder, and click on the CBS folder.

i.         Within the CBS folder open the CheckSUR log file.

j.        Copy the contents of this file, and paste it into your reply.

**Method 3:**I would recommend you to reset Windows Update Components and check if the issue persists.

Answer 4

Thanks Imran

I have seen both of those articles.

Method 1:

There's no proxy or WSUS server. I've checked all the possible other sources that could be blocking updates (ie. Bullguard 10 firewall and antivirus plus the broadband router's firewall) and they aren't blocking the updates. I turned them off completely to confirm this.

Method 2:

As I said in my original posting, none of the suggestions in kb2509997 worked.

Here's an  excerpt from WindowsUpdate.log:
