How to disable access to Microsoft updates

[wilsona]

There is a setting in the OCT file and the GPO to prevent access to updates,
but even when I enable this setting (preventing access), when I click the
Check for Updates button in the Resources section of Word/Excel... options, I
am still brought to the site for updates. Is there any additional settings
that need to be set? Or is there a registry entry that isn't being created
that I can do manually?

Thanks.
