I checked for updates manually and there were a couple for Defender so I downloaded and was prompted to restart. This I did but the menu said it could not install due to an update still running and had a 'retry' button. I used this and the machine shutdown and restarted but will not load Windows. It is hung on black screen (has been for over an hour now), it will not allow me to shutdown via the main switch but is doing something, as it shows a cursor arrow and occasionally the blue revolving circle.
I would be grateful for help, thank you.
