windows10 update

I have already updated to windows10 on both my desktop and my surface pro well not the first gen one cause for some reason it just won't take. I'm assuming I don't have enough space or some nonsense). For people who haven't, it is being reported that it is basically being forced upon you. The dialogue box will pop up and give you a very short window to say you do not want to update otherwise it will go ahead and schedule and install on you. It basically says "TAKE IT AND YOU WILL LIKE IT!"
