Hello Sato, welcome to the Microsoft community, I'll be happy to help you today;
I understand that the sfc /scannow command found corrupt files but could not repair them;
In this case I believe the best solution is to try a factory restore on the system;
Press Windows key + I and access Update and Security;
Click Recovery;
Under Restore your PC, click Start Now and follow the onscreen instructions to complete the restore;
Note: It is recommended that you back up personal files regardless of whether you choose to keep or remove personal files;
I hope I have helped, see you soon!
