Re: Must restart PC each time I want to play
@geekily Do you see anything in the Task Manager related to Origin, Steam, or Sims 4 after you've quit the game and both launchers? Check the background processes list; I used to see an EA background service still running after I quit Origin until I used msconfig to prevent it from running at all. (It's related to the EA Desktop App, but for whatever reason Origin launches it too.)
Please also let me know whether you use OneDrive.
