I clicked on the W10 tray icon that's been sitting there for a while and it started to DL automatically. When I went to stop the DL, it wouldn't. After it completed it and started checking system requirements, etc., I wasn't digging this auto-install crap and wasn't sure what it was gonna do, so I did a quick re-start. My system started acting like it was updating and took about an hour to reboot. I feared my files might be gone if it did a clean install. Fortunately, it was just prepping and allowed me to stop the process once rebooted. BUT..... I don't care for this M$ crap of forcing the issue. I know their goal is to install on a billion gazilion devices, but it shouldn't be forcibly.
