Thanks for the replies Atkinra and Craig53, but the problems that you are describing as fixed are not the same problems that I, and others seem to be experiencing. Perhaps, the original title, ’Mystery
app preventing Windows 10 shutdown after update’ may be a bit misleading, as I am not sure if my problem started after an update, so perhaps we should forget the bit about ‘after update’ and just concentrate on:-
Mystery app preventing Windows 10 shutdown.
When I go to shut the computer down, it says it is shutting down, and a message appears saying, ‘Closing 1 app and shutting down’, with a message below stating ‘This app is preventing shutdown’.
It doesn’t give any indication of what app is preventing shutdown, and no apps appear to be running when checked.
If left alone for a few seconds, the computer does shut down by itself, but it does this every time at shutdown, when it clearly should not.
There is another message that appears saying, ‘To go back to your work, click Cancel, and finish what you need to’, but there is no work to finish, no apps are open.. If I click on ‘Cancel’, during the shutdown process,
and just restart the shutdown process again, the computer shuts down properly, this time without any apps warning.
The problem, (for me), is not stopping the computer fully shutting down, but the warning message that comes up every time on shutdown is infuriating, as it shouldn’t be there.
