Well if they haven't tested it on an Asus Z87 motherboard, with an Intel i7 4770k and a Samsung 1TB SSD, then they really haven't tried very hard, have they? It has absolutely NO additional hardware, cards, etc in it. From what Mr Larrington says, it appears they just rolled out the updates in the wrong order. That is just plain incompetence, for which they should pay, EVERY single person who it has cost money.
I'd liken it to me taking the car to the garage, and they tell me it needs a software update (it did, when it was serviced) and when I go to collect it, they tell me that there was a problem with the update, but its OK, they've sorted the update, but in the process they've removed the seats and the wheels, and I'll have to pay to get them refitted, and also find where they have hidden them.
Yes, it a complex business, but if you can't do it competently, don't claim you can, and charge money for it.
By the way, the car software update went just fine. Luckily it wasn't for the "infotainment" system, which runs Windows CE
