does anyone know the definitive solution to get the restore health option to repair a damaged component store? i ran 10 on nearly 10 machines but on several the big updates always fail to install, had this problem since windows 8, i try the component repair option and it always says the error about couldn't locate source files, even when i specify the location correctly. i got the point where i haven't installed any updates in months because of this "bug", calling it a bug as it's an ongoing issue, never happened till they started doing those massive hotfixes. I just upgrade the whole os when a new version goes to release. just wondering if anyone else has this issue and found a fix?
