Is this done without any notification to the user? Microsoft doesn't say that certain commands must be issued to get Windows 8, if online, to attempt to repair itself. "Will attempt to repair itself" is a bit perturbing.
#How to repair corrupted files in windows 10 update
If there was file corruption, I might not be able to enable it or, perhaps, the corruption might have been less extensive if Windows 8 had been able to access Windows Update and repair itself earlier. For instance, in my case, if I don't want to place an image to be used somewhere on my little home network and specify that in Group Policy, but expect Windows Updates to be used, that means I should not have WU disabled most of the time.
And secondly, you won't have to re-install all the Windows Updates after re-installing Windows.Īccording to the Technet articles that relate to this issue, Windows 8 will attempt repair ON ITS OWN if ONLINE, using Windows Update, unless configured to use a different network source in Group Policy where the configuration is the same as that for Features on Demand. So why use this method instead of simply re-installing (or upgrading) Windows? Well, first off, you keep all of your files, applications, and settings. If you re-run SFC /scannow after you perform these steps, you will notice that it won't find any integrity violations, which means that all corrupt Windows files are fixed. Windows will now download and replace any corrupt files. If SFC /scannow is unable to fix some of the corrupted files (EDIT: This command only seems to work on Windows 8 or later):Ģ) Type in "dism /online /cleanup-image /restorehealth" without quotes, and hit enter. Windows will check for and attempt to repair any corrupt files. If your PC has corrupt Windows system files, here is how you can fix them without re-installing Windows.ġ) Open up an elevated command prompt (cmd with admin rights)Ģ) Type in "sfc /scannow" without quotes, and hit enter.
