SFC /SCANNOW Command - System File Checker

How to Repair Windows 7 System Files with System File Checker​


   Information
The sfc /scannow command (System File Checker) scans the integrity of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible.

   Tip
If you get the Windows Resource Protection Could Not Start the Repair Service error when trying to run SFC, then make sure that the Windows Modules Installer service is enabled, click on Start, and set to Manual.

Services - Start or Disable

OR

Copy and paste the command below in the elevated command prompt, and press Enter. After the Windows Modules Installer service has started, try running the SFC command again

net start trustedinstaller

   Note
The KB3022345, KB3035583, and KB3068708 updates will cause SFC to give you a false mismatch message in SFC for files related to these updates.

You can safely ignore these results in your SFC details since it will not affect SFC from being able to repair other system files.

   Warning
Be aware that if you have modified your system files as in theming explorer/system files, running sfc /scannow will revert the system files such as explorer.exe back to it's default state. Make the appropriate backups of your system files that you have modified for theming if you wish to save them before running sfc /scannow.

CONTENTS:
  • Option One: To Run the SFC /SCANNOW Command at Boot
  • Option Two: To Run the SFC /SCANNOW Command in Windows 7
  • Option Three: How to See and Read Only the "SFC" Scan Results from the CBS.LOG



OPTION ONE

To Run the SFC /SCANNOW Command at Boot


1. For how, see METHOD TWO at this link: SFC /SCANNOW : Run in Command Prompt at Boot

   Note
Using OPTION TWO below is recommended if able.

If you would like to get help with your SFC issue, then be sure to upload and attach your sfcdetails.txt file from OPTION THREE below in your post.





OPTION TWO

To Run the SFC /SCANNOW Command in Windows 7


1. Open an elevated command prompt or an elevated PowerShell, and do step 2 or 3 below for what type of scan you would like to run.


2. To Scan and Repair System Files
NOTE: Scans the integrity of all protected system files and repairs the system files if needed. Please see red WARNING box at the top of this tutorial.
A) In the elevated command prompt, type sfc /scannow, press Enter, and go to step 4 below. (see screenshot below)
NOTE: This may take a little bit to finish.

Command-1.jpg
3. To Only Verify if the System Files are Corrupted
NOTE: Scans and only verifies the integrity of all proteced system files only. This command will not change your system files as in the red WARNING box at the top of this tutorial.
A) In the elevated command prompt, type sfc /verifyonly, press Enter, and go to step 4 below.
4. When the scan is complete, hopefully you will see all is ok like the screenshot below.

   Note

  • If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 or more times to completely fix everything that it's able to.
  • If not, then download and run the 32-bit (x86) or 64-bit (x64) System Update Readiness Tool for your same installed 32-bit or 64-bit Windows 7, restart the PC afterwards, and try the sfc /scannow command again.
  • If still not, then try using OPTION ONE above to run the sfc /scannow command at boot.
  • If still not, then you can attempt to run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.
  • If still not, then you can use the steps in the TIP box in the OPTION THREE section below to manually replace the files that SFC could not fix if there are not to many fix.
  • If there are to many files to manually fix, or you prefer not to use OPTION THREE below, then you could do a repair install without losing anything.
If you would like to get help with your SFC issue, then be sure to upload and attach your sfcdetails.txt file from OPTION THREE below in your post.


Finished.jpg
5. When done, close the elevated command prompt.



OPTION THREE

How to See and Read Only the "SFC" Scan Results from the CBS.LOG



   Note
When SFC runs, it logs it's actions into the C:\Windows\Logs\CBS\CBS.log. The steps in this option will show you how to see only the specific SFC entries with the [SR] tags in this CBS.log. This can be helpful to show you what files SFC could not fix automatically if you wanted to try and manually replace them.

1. Open an "elevated command prompt" (right click -> Run as administrator).

2. In the elevated command prompt, copy and paste the command below, and press Enter. (See screenshot below)
NOTE: This will place a sfcdetails.txt file on your desktop with only the SFC scan result details from the CBS.LOG in it.
Code: 
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"
sfcdetails.jpg
3. Close the elevated command prompt.

4. Open the sfcdetails.txt file on your desktop to see the SFC scan details in the CBS.LOG.

5. You can safely delete the sfcdetails.txt file afterwards if you like.
   Tip
If you need to replace a corrupted system file that SFC cannot fix, then this will show you how to by extracting a new copy directly from your Windows 7 installation DVD.

Extract Files from Windows 7 Installation DVD





That's it,
Shawn

mmc.exe file corrupted

I have run sfc /scannow 4 times and each time the results are the same. The log says the file and its' backup are corrupted.

I am running Windows 7 Professional 64-bit on a Dell Inspiron 620 with 6 mb of ram.

The sfcdetails.txt file is attached.

I will appreciate your guidance as to what I now need to do.

Your SFC details show that the file below has a hash mismatch. You can see if any of the options in the blue note box under step 4 in OPTION TWO may help.

Brink - I have many many many ntsf error messages after each reboot of Win 7 Pro 64-bit. (If you want to see how that started, check out http://www.sevenforums.com/general-...e-win-10-no-help-post3138595.html#post3138595 .)

Just now, in Win 7, I ran sfc /verifyonly and the CBS log reports errors. (And there seem to be amazingly long CBS "persist" .cab logs in the same folder from the past few days that I have not opened up.)

Question: If I run sfc /scannow, is there a downside? Could it wreck my Win 7? (Not the end of the world because I really haven't started using it yet. Worst case, I could reinstall, even if it takes a whole weekend. But another lost weekend)
Important detail: My Dell Optiplex 7010 Desktop is now dual-booting Win 7 Pro 64-bit and Win 10 Pro 64-bit. (I got the Win 10 by letting my Win 8.1 upgrade, then re-installed the Win 10 from a media creation USB.) The Win 10 seems to be working OK and I want to keep the dual-booting. Does that change your thinking?

Thanks.

Hello glnz, :)

A sfc /scannow command will not affect anything other than repairing corrupted or modified system files.

Brink - thanks to your thread here, I've run sfc / scannow a number of times on the Win 7 Pro 64-bit side of my dual-booting Dell (including three times in safe mode), and there are now very few error or warning messages in event viewer. Very nice. BUT ...

The sfc / scannow end message still says that it could not repair some corrupted files (don't have the exact language). And the CBS.log is not exactly user-friendly.

Should I attach here that CBS.log? Would you have time to look and advise what it's actually saying?

If this isn't exactly the right place, is there a forum dedicated to medical advice for CBS.logs?

Thanks again.

I am guessing this makes sense, as I have UNinstalled various MS updates that are designed to prepare my Win 7 to ascend to Heaven and become Win 10. I prefer my terrestrial Win 7. But just a guess.

What do you think?

Many thanks.

These errors are perfectly normal - and MS's fault. There's nothing amiss here
If you want to get rid of them you'll have to uninstall KB3068708 (and possibly KB3022345) and hide it/them

Yep, it's just a false hash mismatch from the KB3068708 update. There's nothing that needs to be done or to worry about. :)

NoelDP - Per your suggestion and a number of other comments, I uninstalled those two updates (in elevated cmd using wusa /uninstall, which can be repeated immediately until you know you got all copies of each update).

And ... voilà! A new sfc / scannow "did not find any integrity violations". Progress!

Many thanks to Brink and you!

Now what to do about diagtrackrunner.exe, which still appears (once only) in my c:/ drive? I have read that it can't be deleted. Please send me links to any good instructions for killing that one.

Also I still have an old but important XP SP3 machine that can run - Optiplex 755 Desktop w 4GB RAM and Momentus XT hybrid HD-SSD 500 GB hard drive.

There should actually be at least 4 different copies of diagtrackrunner.exe present (if you'd kept your machine up-to-date) ;)

Why would you want to remove it?

Just for info... the first two were in KB2952664 and KB2977759 - after that I lose track a little... but I think the later ones are all associated with KB2952664 versions (it's been updated quite a few times since first release in January!)

NoelDP - It might be a stealth "phone home" app to Microsoft. Please google it - many articles - it's linked to the updates I've been trying to get rid of and for which I needed Brink's thread here to repair my machine.

But that's "enuff" about this side topic. Let's leave this thread to Brink's great advice about sfc.
