"Critical error: Start menu and Cortana aren't working"
Hey, I upgraded to Windows 10 on my laptop last night from 8.1 and it had been working fine this morning. However in the afternoon I got a notification that there had been a driver failure and I should restart to repair it. Ever since I have though I've been having difficulties. After I log in I'm stuck on a black screen with only the cursor visible. If you leave it for about 10 minutes eventually the desktop appears, however I'm prompted with the error message in the title and the task bar hasn't loaded. If you try and click on the task bar you eventually get the pop up "Microsoft Windows: the application is not responding" and it gives me the option to end process which does nothing. I'm unable to access control panel, I can use ctrl + alt + delete, however I can't launch task manager.
Booting in safe mode I don't get the critical error, however aside from that the situation is identical. I've tried resetting the PC, performing a system restore to before the update, and start-up repair,all to no avail.
I'm completely out of ideas, if anyone could give me any help I'd be very grateful! Any other info needed just ask!
