Julian has been sick and so hasnt been on, I checked and I am missing those 23 files same as him. Looks like it must be from a bad update that MS pulled.
So I will post the files I do have, then you will run the scan again and then any it reports you will need to delete from
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages"
You will have to change the permissions of those keys to be able to delete them, but once they are removed we can see how it does.
Here are the files
First grab the zip file off this page and apply the reg file it in to add the take owner ship to the right click menu in explorer.

I have attached the missing files, extract the files out of the attached zip file and put them in the C:\Windows\servicing\Packages\ folder.
Then run my pre-scan again, put a check on the box to have it add the cat files back to the database.
