Any help
Shane:
M program doesnt do anything to the system files. 90% of the repairs are all in the registry, so normally just restoring the registry to before the repairs is all that is needed.
The pre scan just looks for missing files and signatures, the files it knows to look for it pulls from "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages"
That is the list of files that are suppose to be in the packages folder. The pre scan loops through that registry key and if there is an entry in there but the file isnt in the folder then it will show as missing. Then after it looks for any missing it then calls the windows api to report if the files have a good signature or not, that is just a true/false return.
Cat files have their digital signature on them, the point of a cat file is to hold the hash values of any files types that cant hold a digital cert, in this case the .mum files. They are just text files in xml format you can open in notepad. So when the programs asks windows if the hash is good for that mum file windows goes and checks the cat database, if the cat file isnt there or if it is and the mum files was changed somehow then it will report back as bad.
Now if you installed any updates after the registry backup then those updates could have simply removed some older updates and thus the files would be gone and it would also be removed from the registry path I gave you. But if you restored the registry after that happened then those would show up in there again and thus the program shows missing files.
If that is what happened then I would just ignore the pre-scan. But remember the program doesn't remove or modify any of those files or any system files. The only files removed are temp files and the cache from windows updates when you run the windows updates repair. Otherwise everything is done in the registry :-)

Thanks. So restoring registry will put back all file security as they was before. That I didn't know.
No updates can be installed, 14 now. Fails each time, and windows sucks ao bad and you can't remove any updates as that fails also. No way of reinstalling ones that are not listed as it says already installed.
Shane:
Restoring the registry will put back the registry and its permissions. The file permissions it doesn't, but only for Windows 8 I only have it set the permissions back to default, I don't change the permissions like I do in Windows 7 and older because 8 is so far the easiest OS to break. If one permissions is out of place, or one folder is missing or anything it just bombs out.
The problem is with each version of Windows each thing relies on something else. So when one thing fails down the line you have no clue what. So I am worried 10 will be even worse.
Perfect example in 8 is if a certain registry key has its owner changed from system to anything else the apps will all fail. Even when the owner is administrator and system still has full permissions, every app will still fail.
There was also another one where if a folder was missing the apps wouldnt download and update. Instead of the app store making the folder it needed it would just give a unhelpful error message and the user would have no clue why it failed. This was nothing more than a temp folder for the downloading of the apps, it didnt even make the folder! How the crap is that not a bug? lol
This is also true with updates, and as another thing as well the optional features list in the add/remove programs, if it encounters a single error, not matter how small when reading the packages files to know what to list it just bombs out and doesn't continue loading the ones it could read, so the list is just blank.
The real problem with Windows, they don't do ANY kind of error handling. So hit even the smallest error and everything goes to hell. I never understood why they did this.

I cant add .net3.5 bombs out, dism errors with error code 5. Update fails.
Seems since I ran all fixes, the system is worse.
Anyone have a list of all updates since SP1 and know where they are are referenced in registry. And have an app to remove references easily.
Shane:
I run my windows repair on about 10 to 12 windows 8 machines a week from my customers, never had anything that is happening to you happen to any of those machines. Any time there was a hiccup restoring the registry is all that was needed.
Something else is going on, and talking to you over multiple threads is making it hard for me to keep track lol
I will continue with you in the other thread :wink:
