Ever since i downloaded a program called Background changer for the Windows 10 login screen, whenever i run sfc scans it says it was unable to fix some of them.I open the cbs.log file and i always get the same errors about the windows.ui.logon.pri file.I've ran a script that i found here in this forum called SFCFix which sort of claimed to solve the problem with this corrupted file, the script succeeds but if i ran sfc again i get the same thing.I'm attaching below the part in the cbs.log in details.Click image for larger version.
