Windows 7: Extract Files from Windows 7 Installation DVD

These files were clusapi.dll, RacEngn.dll and Symphony.psd.
Working on the assumption that two corrupt systems file were more a hindrance than a help, I used the tutorial to extract from an installation DVD, copies of the corrupt files and copied them into the system 32 folder after having first taken over the ownership plus total control as administrator of the two corrupt system 32 files.
And got a O/K result.
The System Restore function is now fully operational and can be used by not only me but programs like Windows Up-Date etc.
I have return ownership and total control to TrustedInstaller as shown in a thread followed from this tutorial.
The only thing I have not be able to do is return the permissions of the administrator to the default.
Does this matter if the owner is TrustedInstaller or can the administrator inadvertently change anything because it has still got full control permissions.
Best Regards Rustydog

Great news Rusty.

It really doesn't matter much to leave "Administrators" as the owner vs "TrustedInstaller". It's just better secured as "TrustedInstaller". :)

Hi This article is much more useful than some of the articles by microsoft in their help article. It clearly says that sfc /scannow checks and repair the corrupted files as given in the top of the tutorial.
But i want to know, how to know the files that are repaired by this scan and the files that are not repaired by this tool.
Because txt shows repairing and at the last of the text file, scan which is 100 percent complete, it shows that all the error shown in this scan have been successfully repaired. How to know these things.
The command also shows that some files could not be repaired in the command prompt
Hope somebody would reply

Hello Jraju,

OPTION THREE in the SFC tutorial below can help show you how to view the SFC details from the CBSLOG file to see what files SFC could and could not repair.

SFC /SCANNOW Command - System File Checker

Hope this helps, :)

Hi Thanks Brink
But what about the message at the end that all the files used by this tool has been successfully repaired. There are some files found that cannot repair member file and a long path. But at the end it shows that all has been successfully repaired. Is there any command to get exclusively what are those entries in the cbs log or sfcdetails.txt that pertain to the problematic lines in the scannow option/
Should we try to copy those files,from the method you prescribed. It would be easy if the files having problem alone could be copied using this method.
From your article i understand that sfc /scannow command tries to repair those files which are found in the installation directory or source from the computer directory. If not , we have to get from the dvd as per your tutorial. But how to know, which files are not repaired. I read an article in msoft article that repairing or repaired means that sfc can may copy these files, without an assertion of the facts on the instructions. cannot repair files , what should be done how to know the path of the file from the dvd. Please your tutorial is the best that could be found in the surfing
Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7. This article could not describe what these commands at step is doing. Totally confusing, how it will fix some files by taking owner ship in the total sfc text
How to analyze the log file entries that the Microsoft Windows Resource Checker (SFC.exe) program generates in Windows Vista by refering this article , in entry, data, explanation, the description is totally confusing as how to find . They could have given samples.
Your article is the best on the subject, as the msoft article lacks in explanation to the fact that sfc command does not actually repair anything, eventhough it shows as repaired as given in the red lined note.
I hope no one would be willing to reinstall windows as it is a last step. You have to loose all the programs and it takes huge efforts. Thanks for listening

Yes, the sfcdetails.txt file from OPTION THREE will give specific details on what was and was not repaired by SFC. If you like, upload your sfcdetails.txt file, and I'll be happy to take a look at it. It most certainly can be a bit overwhelming if your not used to reading it. :)

Ok. I have done 3 scans and my system could be repaired oby sfc for most of the files. But some of the files , like desktop.ini and music , jpeg files could not be repaired. Anyhow for your perusal , i am sending the latest sfc details.txt.
But let me know clearly the repairing is repaired files from resource
repaired is repaired files from resource
cannot repair means that is not in the resource store.

But pl tell me that by taking ownership, how the sfc problem could be fixed as i have detailed in my link STEP2. Should it mean that c: instead of E as usual. Because mostly os is installed in c:
Please, i substitued c: in place of e, it allowed the permission, but the last command did not work. Please try and give me your considered opinion on how to go further about it.
Thank you for your excellent coverage with easy to understand. Yesterday only i tried the sfc three times and most of the problem have gone.
My wpfiles have been deleted by generic trojan and it was removed from using malware bytes. SFc could not complete then.Now it runs 100%. Could the trojan remove the protected files as easily as found in the mcafee article
Generic.dx!A0CD0A91A611 | Virus Profile & Definition | McAfee Inc.
It simply removes 20 files eh. Expecting reply

There's just to many files to list and go over one by one, but they are nothing to worry about either. They are sample files from these folders:
  • C:\Users\(user-name)\Music\Sample Music
  • C:\Users\(user-name)\Photos\Sample Photos
  • C:\Users\(user-name)\Videos\Sample Videos
  • sample .mp4 and .mpg files in: C:\Windows\Performance\WinSAT
Yes, a virus can do just about anything once allowed to be infected by it. Personally since a virus was involved, I would recommend to do a clean install of Windows to help make sure your system is clean.

Hi Thank you Brink for pointing me. But, the analysis you could do may kindly be detailed, so that any could do it. I am really fascinated by your replies and tutorial. Daily i visit this site for tutorial .
