Windows 10 1909 in Software Posted 3 hours ago · Report reply I'd also suspect that is the probable explanation. It's taking too long to complete a task and so times out with an error, then it immediately tries again and completes sucessfully - which is why the system then runs normally. Of course that still doesn't explain just why it's taking too long and timing out in the first instance. Possibly background tasks loading at startup? Try Settings>Apps>Startup to turn them off?
