Windows 10 installer already loaded on my Win7 laptop (in a hidden windows~bt folder). I guess there is a timebomb attached that will kick off at midnight EST. That should be interesting.
The gaming PC (on which I'm typing now, 3rd system of cobbled together parts) is sticking with Windows 7 until the other two get 10 and it seems stable enough. Can't jeopardize my Hearthstone and WoW time.. oh no..
