I play a game called fortnite by epic games and twice after game updates i get an error that i am missing a certain dll file -- api-ms-win-downlevel-kernel-32-l2-1-0.dll . I have to delete and reinstall the entire game to get it to run again . I asked the game company about the error and they said to ask microsoft support. Microsoft support was useless. From what I have read the file is basically microsoft spyware used to track what your computer is doing and sending the results somewhere.
