Hello, I am thinking about trying out the Windows 10 Technical Preview, however I have some questions about it. How stable is it, as far as bugs, crashes, compatibility, etc.? I know there will be bugs and that it's not the finished product. I am just trying to decide if it is going to give me problems which would be reason enough to go back to the operating system I am currently running (Windows 7). I am planning to take the upgrade route, rather then formatting and losing my configuration and programs. So is there anything that will break/not work? Is there anything that will be removed?
