You ever walk away from your Windows 7 computer for an hour and came back to see your PC installing Windows 10 without your permission? Me neither, until tonight. I can't believe this really just happened. I'm reading through what people are saying on other forums and sites and there is not one good thing. People saying it's making hardware fail, people saying their stuff is erased. My PC is 5 years old. Looks like I am in for a rough night.. It's currently at 18% and I am sitting here just thinking about all the documents and shit I may losing.. So, take it from me. Back your shit up. And do whatever you can to make sure your Windows PC isn't going to auto upgrade on you.
