If you experience a Windows problem or Windows update problem, you may try to run System file check (SFC) and to fix it.
To run a system file check (SFC)
Go to start>Type CMD
Right click and run as Administrator
Type sfc /scannow
It may shows one of three possible results:
Windows did not find any integrity violations (a good thing)
Windows Resource Protection found corrupt files and repaired them (a good thing)
Windows Resource Protection found corrupt files but was unable to fix some (or all) of them (not a good thing) If you get this message run DISM as described below
To RESTORE health (recommended)
Use DISM /Online /Cleanup-Image /RestoreHealth to scan the image for component store corruption, perform repair operations automatically, and records that corruption to the log file. This generally takes 15-30 minutes depending on the corruption and size of the partition.
Note: 1. You may have to run this up to 3 times to fix all the problems.
2. After running DISM it is a good idea to re-run SFC /scannow to make sure all the issues were fixed.
3. If you get the error message “cannot find source files”you need to have an ISO file mounted and need to specify where it is located with the below command. The ISO must be exactly the same version as the running OS. An ISO of 10586.0 will not repair a running system of 10586.35 because it has additional updates and files.
