If, however, the System File Checker fails to replace your file there is a second option. Windows will then go on to replace any files that have been modified or corrupted with the correct and original version of this file.
This checker scans your system files, alerting you where there is corruption or any other changes. Windows, aware of this problem, have built a System File Checker in their latest update of Windows 10. Ever been power typing on your keyboard with 100 tabs up on google, trying to get a really important piece of work finished and this horrific blue screen pops up? The immediate reaction for many is ‘why on earth did I not save that file’ or ‘please please please can this not be due to a corrupt file.’ If it is the latter, we know how you feel and are here to tell you how to fix it.
