SCCM Clients failing to install windows updates

Quick nod in Wayne's direction for this one:
http://ixrv.blogspot.com/2011/05/sccm-failing-to-install-windows-updates.html

Problem:
Windows updates not deploying to SCCM Clients

Cause:
Proxy value set in registry here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\WinHttpSettings
Resolution:
Deleted the value WinHttpSettings

More information on the WinHttpSettings registry setting and how the Windows Update client determines which proxy server to use to connect to the Windows Update Web site:
