Windows 7: sfc /scannow Unable to repair files

11 Apr 2015   #1

Windows 7 Home Premium 64bit
sfc /scannow Unable to repair files

Hello everyone. I need some guidance on my current issue for my laptop.

Step 1. I open the command prompt (ran as administrator) & use the following command: "sfc /scannow"
to scan for any errors.

The result was the following:

"Windows Resource Protection found corrupt files but was unable to fix some of them"

Then I use: find str/c: "[SR]" %windir%\logs\cbs\cbs.log>sfcdetails.txt

but sfcdetails.txt came out empty.

Step 2.
After some research, I found out you need run "DISM" on cmd to fix any errors if the first step wasn't able to.

The result for this was the following:

" Error: 87

The restorehealth option is not recognized in this context. For more information refer to the help.

The DISM log file can be found C:/Windows/Logs/DISM/dism.log "

I have provided both CBS and DISM log files in the following links:

1. CBS

Forgot to mention, the reason why I started doing all this is because I was suggested since I'm having trouble installing 3 windows update.

1. Security Update for Windows 7 for x64-based Systems (KB3033929)
2. Security Update for Windows 7 for x64-based Systems (KB3035131)
3. Security Update for Windows 7 for x64-based Systems (KB3046049)

I get the following error code: 800F0900

The Windows 7 software seems to be running without any problems. The only issue is with the windows update. But who knows, it might be having other problems that it hasn't made an impact yet to notice it.

Should I be concern about my current situation ? Please let me know

Hello easyL and welcome to Seven Forums.

As indicated in the "Note" box of the SFC tutorial (under Option Two, Step 4) it's sometimes necessary to run the System File Checker scan three times and rebooting after each scan before the files can be repaired. The same "Note" box has some additional suggestions on how to proceed if files can't be repaired.

SFC /SCANNOW Command - System File Checker

The final "Tip" box (under Option Three, Step 5) has a link to another tutorial on how to extract files from your Windows 7 installation disk to replace missing or corrupted system files in your current Windows 7 installation.

Another possible solution is to do a Repair Install. If successful it will fix your currently installed Windows 7 and preserve your user accounts, data, programs, system drivers, etc. As you mentioned, your computer is having problems with Windows Updates. There could be other problems you're not aware of and a Repair Install could fix them as well.
