System File Checker found problems.

Hi, I spend the last week discovering my new computer. Updating some drivers, downloading some software, things here and there. The computer is not slow. Sometimes it shows compatibility problems with some software and games, like every Windows 10 user seem to have in the start.
But what got me was the internet. (THIS IS NOT AN INTERNET PROBLEM) It performs in an acceptable way. Not slow, not fast. I decided to run a scf scan to see if anything was happening since other computers had a much faster Wi-Fi than me.

It showed me this message:
--------------------//
Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.
--------------------//

I got a little scared so I decided to check the Log. But I don't know how to read those thousands of lines.
Can someone tell me from the CBS log what is wrong and how to fix it? Thanks.
