Your SFC log is interesting - something had ripped out WIndwos Defender (or MSE?) by the roots, instead of just switching it off.
The remaining errors after SFC had fixed those, are caused by KB3022345, and can be ignored - although KB3068708 will update that one, and cause the same errors in a higher version number.
If you want to clear those errors, uninstall KB3022345, and hide both that, and KB3068708 so that they don't reinstall until MS gets around to fixing the errors.
The background CBS data gives some interesting errors, which I don't recall seeing before...
Code:

I'm unclear as to exactly what is write-protected (file system or registry)
Let's start with the obvious and easy - the file system
Please open an Elevated Command Prompt, and run the following commands
ATTRIB C:\Windows\System32\config\COMPONENTS
ATTRIB -R C:\Windows\System32\config\COMPONENTS
ATTRIB C:\Windows\Servicing\Packages\Package_7_for_KB2506014~31bf3856ad364e35~amd64*.*
ATTRIB -R C:\Windows\Servicing\Packages /S
