Solve : Unknown files on root of C: drive?

1.	Solve : Unknown files on root of C: drive?
Answer» On my computer I have many unknown small files that I never installed. I tried to DELETE a few but they WOULD not delete. I am no idea what to do with them. I attached a screenshot of a few of the unknown files. Please let me know if you have any suggestion to what I should do to solve this issueSomething HAPPENED in August 2017, over 2 years AGO. What do you mean they 'would not delete'? It would be nice to show a file extension....When I tried to delete these files they acted like they were deleting but they REMAINED on my drive. I managed to get Admin rights and then I did delete some but when I rebooted it took forever so I recovered them. Here is another partial screenshot of my c: drive with file extensions.
