You can get into Windows Recovery Environment from the login screen, by clicking Shutdown, then holding down the Shift key while selecting Restart. To fix these files you have to run SFC command through the command prompt in the Windows recovery environment.
Keep in mind that System File Checker (SFC) cannot fix integrity errors for those system files that are currently being used by operating system. Once operation is complete you will get the message “Windows Resource Protection found corrupt files and successfully repaired them.” or “Windows Resource Protection found corrupt files but was unable to fix some of them”. It will take a while, so please be patient. Alternatively, you can press Win + X key combination which will open the menu where you can select Command Prompt (Admin).
To execute this command, you have to run command prompt as administrator. Many users are familiar with the sfc / scannow system file integrity check command, which automatically checks and fixes protected Windows system files.
