My problem appears to be solved, I contacted the Microsoft Support Centre (in Malaysia) who had no knowledge of this KB2862330 conflict. I explained that it was reasonably well known and was being discussed on a number of internet forums. I sent them a screen-shot of the error meassage and got a quick reply that the problem was with the Lenovo software in my laptop.
So I contacted the Lenovo Service Centre and explained the problem to them. They asked for some details from the error message and immediately identified the problem which was, seemingly, known to them.
Lenovo sent me an e-mail with a link to the corrective software on their website. Once all required actions had been completed - it took about 45 minutes - my laptop was again behaving normally. Hope this helps.
