So, my computer died and I turned it back on when I plugged it in. However, as I signed into Windows, it said Preparing Windows, which was a little odd. When the Start Menu came up, over half of the panels were done. I went into my desktop, also a lot of stuff gone. My settings were changed, the windows are green, the toolbar doesn't autohide, and my background is changed to... a Bing image? With a Bing Toolbar now randomly popping up? Is this a virus? Has Microsoft literally forgeted up my computer? What happened?
