How do you fix corrupted files found by SFC /SCANNOW?

I am using Windows 7 Professional Professional. About 2 weeks ago my machine started "not responding" when I would run my various software. It progressed to a severe condition and I would have to power down with the power button.

I have run ESET NOD32 Anti-Virus 6 virus scans, Malware Bytes Anti Malware free version and SuperAnti Spyware free version. All of the scans were clean with no infections. I have also run CCleaner.

Last night I ran SFC /SCANNOW four times. Each time the result was "Windows Resource Protection found corrupt files but was unable to fix some of them." Before I ran the last scan I deleted the CBS log that contains the scan results. After the fourth and last scan I opened the CBS log which is l located Local Disk C/Windows/Logs/CBS. The log file was 331 pages long - too long to print out. I tried to find where it told me which files SCANNOW could not fix but I didn't really understand much of the log file contents.

After I ran the four scans the machine ran well today with no "Not Responding" issues - I'm keeping my fingers crossed.

A few years ago when I was running XP Pro I could insert the Windows installation CD into the computer and when SCANNOW ran it would pull the necessary files off of the installation CD if it found a corrupt file.

I have the original Windows 7 Pro 64 bit installation disk. Is there a way to fix corrupt files that SCANNOW is not able to "automatically" fix on it's own?

Thanks very much for your help.

Give this a try. The file was created by kronckew, one of our colleagues. Tested it on my Laptop, and it worked!

:info: Boot to Safe Mode.

Go to Start > All Programs > Accessories > Command Prompt
Right-click the Command Prompt, and select: Run as Administrator

At the Command Prompt, copy/paste (with the mouse) the following text inside the code box below, and press: Enter


When sfc is done, a file named sfcdetails.txt appears.
Please save the sfcdetails.txt file to the Desktop, and post it in your reply.


:info: To run the program a second time, open the Command Prompt, right-click and select: Run as Administrator

This time, type in the following:


Press: Enter

When done, a file named sfcdetails.txt appears once again.

Please save the file to the Desktop, as sfcdetails2.txt, and post it in your reply.

Run SFC 3 times with restarts in between each of them then upload the CBS.log located in C:\Windows\Logs\CBS\CBS.log

Cottonball;

Thanks for your reply. I used kronckew's small program and it worked great. I have attached the sfcdetails.txt to my post as you requested. I tried to run the program a second time as you suggested. When I opened the Command Prompt, right-click and select: Run as Administrator and typed in startsfc it came back to me saying the command was not valid.

Last night I did run the SFC /SCANNOW four times with a reboot in between each scan.

I hope you can read the sfcdetails.txt file and tell me how to fix/replace any corrupted files that SCANNOW couldn't fix.

Thanks very much for all of your help.

artmanphoto,

Let me tell you up-front that sfc /scannow results and the repair of corrupted system files that SFC cannot fix is an area in which my knowledge is just average. The post above was done to make things easier for you, since it is something I used, and it worked.

To replace a corrupted system file that SFC cannot fix, would look at the following resource to extract a new copy directly from your Windows 7 installation DVD: http://www.sevenforums.com/tutorials/42776-extract-files-windows-7-installation-dvd.html

or...

You may be a step ahead with the files that cannot be repaired by doing a Repair Installation following these steps: http://www.sevenforums.com/tutorials/3413-repair-install.html

Someone with expertise in this area will hopefully provide you additional assistance.

Hold on, we have a expert on fixing corrupt files, I'll give him a shout, Tom982. Give him a couple days, he's a busy student.
Don't reinstall or anything just yet.

It's also a myth that running sfc 3 time will help. If the file checker can't find the good file in the winsxs folder, no number of time will help.

Britton30, thanks very much. I will really appreciate any help.

Hi Bill,

Before we begin I just wanted to mention something Gary touched on. I'm currently a student doing a Maths degree and have 4 crucial exams coming up, of which my first is on the 13th, so my time is very limited at the moment and I might not be able to post much (once a day minimum), but I will get you up and running again! So just hang in there and we'll fix this as soon as possible! If you haven't heard from me in a while, feel free to shoot me a PM to remind me - at the last count, I have 24 tabs open that I need to reply to so it's quite easy to lose one in the mix.

Hmm, strangely in all 653,711 lines of your last CBS.log I can't see any sign of SFC being run so let's run it again (now redundant) and get a new log:

SFC Scan

1. Click on the Start
   
   button and in the search box, type Command Prompt
2. When you see Command Prompt on the list, right-click on it and select Run as administrator
3. When command prompt opens, copy and paste the following commands into it, press enter after each
   
   del %windir%\Logs\CBS\CBS.log
   
   sfc /scannow
   
   Wait for this to finish before you continue
   
   copy %windir%\logs\cbs\cbs.log %userprofile%\Desktop\cbs.txt
   
   
4. This will create a file, cbs.txt on your Desktop. Please zip it up and attach this to your next post.

Hi Tom;

Thanks very much for your quick reply - I really appreciate your help. I totally understand about your finals. I would like to try to solve my issues but I am very willing to go slowly when you have the time as this is not an emergency. As you recommend I will run SFC and get back to you.]

It will work out for you, much better than a reinstall. Read Tom's instructions carefully and don't miss a step...like I did the first time.

Thanks very much. The Windows Update Package Replacement procedure looks kind of scary to me - I don't want to mess anything up. I will follow Tom's instructions.

Hi Tom!!

Have a great New Year! The same goes for Britton30, Bill and dbseven.

Just want to make you aware the there are two individuals posting here, one is the OP, artmanphoto (Bill), and the second is dbseven, which --->> needs to start his own topic. <<---

Looks as if you opened the two .zip reports, and they do not belong to the Original Poster, Bill. :huh: The priority goes to him. He started this topic!



--->> Bill, please hold off until Tom confirms what he wants you to do!!

OK, I will wait for Tom to confirm what he wants me to do.

Thanks, Bill

Glad you got this in time, Bill.

As Tom forewarned:

Warning: this fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good. If you are after assistance, please start a thread of your own

It appears he used reports that were not yours!!

By the look of things, it looks like I'm the one who needs to read the logs carefully!

Hey Cottonball,

Happy New Year to you, and all the others, too!

Thank you so, so much for picking up on this! What would I do without you? I have no idea how I managed to do that, but we've managed to avert the crisis now - fortunately it wouldn't have actually caused any harm, it will have just fixed files that didn't need to be fixed.

Hi Bill,

I'm so sorry about that! I've never done anything like that before, but I assure you it won't happen again.

Okay, now I'm actually reading the right logs, I can see the problems. While parsing the CBS log to sfcdetails.txt makes it nice and easy to read, it actually cuts out some of the crucial information I need to be able to fix this so before we can continue, I'll need a copy of your full CBS log:

C:\Windows\Logs\CBS\CBS.log

Copy this to your Desktop, zip it up and attach it to your next post please!

Tom

Bill,

I believe this is what Tom wants you to do next:

Nope He's already done a scan, I just need the full CBS logs to see the log.

Well, it is my turn to goof up!!

The score (strikes) is:
Britton30 = 1
Cottonball = 1
Tom = 1


Bill, you are the only one that is doing OK!

Welcome to Seven forums GerbenB. I will ask the mods to make this a new thread for you, it's the right forum though.
