"Killer Updates" - thanks for the advice
Thanks muchly for all the advice - I'll just briefly answer a few of the points.
I appreciate that "tens of millions of Windows machines manage to apply Windows updates without any drama every month". That's true - I'm usually part of the club. But, along with too many others, I 'regularly' get caught out!
I will say that it's an unrewarding and time-consuming task to navigate the official M$ site (will avoid ranting at this point).
I had created various restore points before Windows Updating but, on boot up, it proved impossible to use this option (I won't bore you with details).
As I indicated before the IT engineer made it very clear to me that the problem was with the Windows Update service - rather than "badly written drivers" etc.
IMHO it is M$ themselves should be doing the testing beforehand - not us.
