Windows Updates will not configure

I'm new to this forum so, I've searched the archive to see if someone has already posted a similar problem to mine but can't see it.

I've used 360 on my old PC for ages without a problem; bought new PC at end of July, usual loads of updates to Windows, Firefox, PS Elements, etc as when one gets new software.

All went well for first few weeks, all updates loaded OK then... nine Windows updates appeared, five of which were "important"; PC downloaded these on shutdown but when I switched on I got the message that Windows was "configuring" the nine updates, only got to 15% and failed, then "reverted" to old set up. This happened every time I switched off and on. Tried the "FIX" thing on Windows, this said it had fixed the problem but it has not. I now have fifteen Windows Updates which it will not configure!

I'm wondering if Norton 360 is somehow in conflict and is stopping the configuration? If this is possible, any advice on what I should try?

 

Thanks,

Pete. (old fart, not a computer whizz but I do know which way is up!).
