If you ever get attacked by malware or have install get botched getting the core Windows files can be a pain. You don’t need a support disk, have to reinstall windows, or download the file from some scary site that might be giving you malware. Just do this:
- Right click
Run as Administrator
The scan will take about ten minutes or so. After doing this, the Windows core files should work again. It will give a link to a log that might be helpful if
sfc didn’t work as expected.
