HP - Probably the worst software in the world
My 5 year old all-in-one HP seems to be a decent piece of hardware, in that it (used to) do what it says on the tin, but HP's software - and especially its updates - is AWFUL. (Sorry about the shouting)
The software update that HP said that I should install did nothing that I can see, other than disabling the scanner.
As I'd bought the bloody thing partly for the scanner, I was not much impressed.
As others have said, it is almost impossible to uninstall their software. I once got the instructions from a techie about how to do it, but it looked like a full week-end job. I have a life!
Even though HP finally admitted that it was thier software that caused me the problem, they made no effort to do anything about it, and made no attempt to keep me as a customer.
(Shouting again)..........I HATE them!!!!
