My PC decided to crash while playing Destiny 2, so i restarted it. It worked fine after that but i decided to run the latest windows update since i hadn't gotten around to it and so this problem might not happen again. I pressed update and restart and the messages displayed kept repeating themselves, so i waited about an hour and it was still happening. So, i was stupid as i was, i restarted my pc mid installation. It seemed fine, it booted up the install and found the files again, and got to about 48% on the update when it just booted up my start menu. I logged in and was met by a flashing black desktop, with a taskbar in the wrong place with my icons, which seemed to switch between the desktop and the start menu. Black and gray back and forth constantly, every second or so. I was able to boot into safe mode no problem, but wasnt able to access system restore. After coming back to a normal boot i got the error message "C:\WINDOWS\system32\config\systemprofile\Desktop is not accessible. Access is denied" followed by a black desktop and grey taskbar again sitting in the wrong spot with no shortcuts and i cant even press the start button Help!
