I'm working on my daughter's laptop with Win 10 installed. She says that all of a sudden her start menu wouldn't open, the Cortana search bar wouldn't let her type in it, and she was unable to get onto the network. I was able to get the network running by statically assigning an IP address and noticed that multiple services wouldn't start, like DHCP and RPC.
After a little google-fu, it seemed the issue was due to update or system file corruption, so I ran SFC /scannow. It found corruption but couldn't correct it. So I found the DISM command and ran it under an admin powershell using myriad variations: with/without windows update, without source files listed or pointing to the ESD files on a Win10 installer bootable USB. I even moved sources folder from the USB to the C: drive without success. Every time, it errored out saying it couldn't find any source files. The last command I tried was a command I considered a "hail mary" that I found online: Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:c:\sources\install.esd\1\Windows\WinSxS\wow64_microsoft-windows-r..xwddmdriver-wow64-c_31bf3856ad364e35_10.0.10586.0_none_3dae054b56911c22\
This of course didn't work, either. So here I am. I downloaded and ran SFCFix, but it says it couldn't find any corruption. See the log below. I then tried another SFC /scannow with the same results. I have attached my CBS and DISM logs.
