I ran a sfc/scannow command in cmd prompt and although it was able to find some corrupt files it was not able to repair all of them. So, i tried running it 3-4 times and then also tried running it in safe mode but everytime it gave the same message. Then, i tried running dism /online /cleanup-image /restorehealth command, it ran successfully and was able to repair the files but when i again ran sfc to check if the files were repaired it again gave the same error. What should I do?
