Thanks both, I have tried some of the methods, but no real success. I tried the Fix WU Utility in Whither's post and strange to say it resulted in Microsoft's System Update Readiness Tool that was giving an 0x8007000d code now loading!
The Microsoft utility spent about half an hour thrashing around as though it was defragmenting the hard disk and then one update loaded, but all the others then failed again!
I had just defragmented the hard disk before I tried this utility and afterwards I used the defragmenter again, but it then took about half an hour or more sorting out the scrambled hard disk again after the System Update Readiness tool had run!
Its a bit curious that you have to use a third party fix in order to load Microsoft's own supposed fix which then does not fix things! I have also used Microsoft's Fix It utility which supposedly corrects update problems, again with no luck.
In the past I would have just put in the Windows CD which would have fixed bad system files and picked up all my files whilst doing so without setting everything back to square one. However we now get the OS preinstalled with computers and though CD's only cost pence to make we no longer get the proper Windows version on disk we have paid for, but simply an OEM "repair" disk as a substitute, which must cost as much to make as giving you the proper Windows disk in the first place?
I am not too happy about using the Dell disk just as I used to use the proper Window's disk after reading the following link:-

I guess if needed I will get a computer programmer friend to try and sort it if I need to go back to the start again.
PS. I should add that apart from not loading those updates the computer is working perfectly and pretty fast.
