I was updating my anti virus on my laptop and decided to restart after words to speed things up, the laptop decided to do an update I had no idea was there, about 2 hours of looking at we'll be ready soon and the mouse icon appeared so I clicked it and the blue screen where it said that went a bit of a lighter colour before disappearing and leaving me with a black background with all of my shortcuts all shoved into one corner and a taskbar I couldn't use anything on.
Restarted again and at this point all I have is a black screen with the taskbar (with no pinned icons) occasionally appearing for a split second then disappearing again.
Does anyone know what's going on, how to fix this or even just go back to before that update?
