When I ran sfc /scannow the I get the following output Code: C:\Windows\system32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not supported in offline servicing scenarios. I also tried DISM to restore health but it also fails. Here is the output Code: C:\Windows\system32>dism /online /cleanup-image /restorehealth Deployment Image Servicing and Management tool Version: 6.3.9600.16384 Image Version: 6.3.9600.16384 [==========================100.0%==========================] Error: 0x800f0906 The source files could not be downloaded.
