Windows Update error 8024402C

Got this error recently on a Windows 7 32bit system while trying to do updates.  Previously, Automatic Updates were enabled and it ended up in a Installing 3 of 3 loop.

To fix this, refer to Microsoft’s KB: http://support.microsoft.com/kb/900936
Run each of the following in a command prompt as Administrator:

  • netsh winhttp reset proxy
  • net stop wuauserv
  • net start wuauserv

Previous History
I have renamed SoftwareDistribution to SoftwareDistributionOld and ran updates again but this did not work.

Microsoft indicates it could be from WSUS, security program/application preventing SVCHOST from accessing Windows Update according to their article http://windows.microsoft.com/en-US/windows7/Windows-Update-error-8024402C.

I disabled Symantec Endpoint Small Business 12.1.2 and tried to run updates again but this failed.
I am now running a Malwarebytes scan to make sure there isn’t an issue with the computer such as malware preventing updates.

I manually had installed SP1 on this Windows 7 computer without issue also.  I’ll report back what I find to resolve this problem.

Attempted http://support.microsoft.com/kb/900936 this fix, specifically:

netsh winhttp reset proxy
net stop wuauserv
net start wuauserv

This worked, updating blog post.
