How do I fix my windows 10 error message class not registered

My windows 10 is not working - my window key doesn't work, I can't find settings on my computer, task manager doesn't work, edge doesn't open and I keep getting error message "class not registered"

Did you try SFC \Scannow as administrator @ command Prompt? Google SFC
