Hello,

See if this fix helps you:

Let us know if this helps!

Hopefully Windows 10 will fix the problem you’re having. You could always use disc imaging software like Macrium reflect to backup your 8.1 before updating to 10 then if it doesn’t fix the problem or you experience other problems you can quickly return to 8.1.

It is unfortunately true that upgrades to Windows can make other hardware & software incompatible.

Just thought I'd let you know the problem has been solved following a conversation with an I T guy at work. After describing to him how I restore the computer too factory settings he asked me what I do next. The computer had on it a free trial of Office 365 & Macafee, I would un install those then,thinking I'm doing the sensible thing I would run 'CC Cleaner' 

 This appears to be the problem.

 I've reapeated the steps to restore the computer again but this time without running CC Cleaner. Now both ITunes and Windows Update are running perfecty. Seems to me that CC cleaner is either to abrasive or for some reason it just doesn't agree with my computer. Hopefully you might be able to advise someone else with the same problem in the future. Once again thank you for your help & hope this proves to be some use to somebody else...Alan
