Hello Barry,
Quote from Lucy at MS : ** "Typically the 0x800A1391 error is cause by 3rd party software interference.
A program is preventing the download of the ActiveX controls. Are you
behind a Firewall? Proxy? " </enquote> **

Do you have any browser-popup stopper - type program ? There are a bunch that cause hiccups.
So could add-on download helpers.

If you have AdShield, NetPopup, or any popup ad remover, you need to insure that program is OFF before doing Windows Update.
It can also be an over-eager antivirus program (if you have one) that is interfering.

If none of these are the source, then, if you have a 3rd-party firewall program, try turning that off & then test Windows Update results.

Quoting some items for this error -- from MS Windows Troubleshooter:
It appears to be because the customer can not download the ActiveX component.

#1. Try turning off firewall.
