Hi Shane,
I did not say your pre-scan found missing files. I said I ran your SFC part of tweaking and it found errors which it could not fix. So I then opened a command prompt and ran
Dism /Online /Cleanup-Image /CheckHealth
which says the corruption is repairable.
I then tried
Dism /online /Cleanup-Image /RestoreHealth
Which then said it could not find the files needed
So I tried
I have tried Dism /online /Cleanup-Image /RestoreHealth /Source:wim:L:\x64\sources\install.wim:1
as there is a wim file there on the windows 10 install usb. However it gave the same message about could not find the files
The two logs I attached were from that. Your prelog says
--------------------------------------------------------------------------------
Checking Environment Variables.
Started at (9/21/2015 11:08:17 AM)
This folder in the 'Path' variable doesn't exist: C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static
This folder in the 'Path' variable doesn't exist: C:\Program Files (x86)\NTP\bin
This folder in the 'Path' variable doesn't exist: C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\
Problems were found with the Environment Variables.
You can use the Repair Environment Variables Tool at the bottom of this Window to try and fix these problems.

Scan Complete - Problems Found!
You can use the Repair Reparse Points or Repair Environment Variables tools at the bottom of this Window if needed.
While problems have been found, you can still run the repairs in the program.
But for the best results it is recommended to fix the problems reported in this scan if possible.
If you need help fixing any of the items in the log, just post in the forums at Tweaking.com for help.
