I have never run into anything like this and I am VERY worried about it. I have Windows 10. Last night I went to bed and when I awoke, my desktop was this way and continues to be this way even after restart. I get my desktop background and taskbar/start button, but no icons, no mouse, and no notification area/clock. Hitting the windows key does nothing. The search even looks different, just the magnifying glass, no extra space to type stuff in as it normally does(not that I could). I can't seem to get into safe mode to see if that works, and hitting ctrl + alt + del brings me to a black screen. It's almost like it isn't loading anything, because it restarts almost instantly and doesn't really make any loading sounds. If I go to the bios, it is normal and I actually have a mouse.
Does anyone have any idea what this could be? I have no idea what could have prompted this to happen as it was fine before I went to bed. Thanks so much to anyone trying to help out.
