Frequent corruption detected

antares · 07 Apr 2023

Hi all, as part of Windows maintenance I check for corruption with the "sfc /scannow" and "DISM /Online /Cleanup-Image /CheckHealth" commands on a monthly basis. Since I installed Windows about 5 years ago I never had corruption, but for the last 2 weeks sfc /scannow is detecting corruption showing this message:

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files and successfully repaired them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

So immediately after I run sfc /scannow again and everything fine, but for some reason after reboot corruption appears again, this case being repeated about 5 times in the last 2 weeks. Any hint? Thanks

Hello @antares,

To output the results for sfc ONLY, Copy & Paste the following command into a CMD Prompt and press Enter. It will create a sfc_Details.log file on your Desktop. If you have a relocated Desktop, then change the output Path accordingly.

Code:


findstr /c:"[SR]" %WinDir%\Logs\CBS\CBS.log > "%UserProfile%\Desktop\sfc_Details.log"

I hope this helps.

Hi Paul, yes, I did run that command to generate the sfcdetails.txt file on my desktop, but unfortunately I get lots of lines that I'm unable to interpret that read as follows (I extracted just a few lines as samples):

2023-04-07 04:43:39, Info CSI 0000000a [SR] Verifying 100 components

2023-04-07 04:43:39, Info CSI 0000000c [SR] Verify complete

I also get lots of lines in the following style:

2023-04-07 04:44:26, Info CSI 0000022f [SR] Repairing file \??\C:\Windows\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\RetailDemo\\retailDemo Setup.js from store

You can see what the repairs are [within the overall SFC records] using Option 5 of
SFC - TenForumsTutorials

You can play around with exactly what entries you extract from SFC records***. I use this to extract just a list of repairs to a text file on my Desktop.

Code:

findstr.exe /c:"[SR] Repair" %windir%\Logs\CBS\CBS.log >"D:\Desktop\%ComputerName%-SFCResults-Repairs.Log"

Replace my D:\Desktop with the path to your own Desktop.

You can do this each time to see what repairs are being done - perhaps they are the same ones every time.
Some faults & their repairs are trivial so do post your results here for others to consider.

Best of luck,

Thanks Try3, that is handy

I've now stopped fiddling with my last post. I've added a link to a description of all the SFC shortcuts I use.

All the best,

This bat script may be useful:

It runs scannow followed by restorehealth followed by scannow to see if repairs remain fixed.

If there were to be uncorrected problems an in place upgrade repair is often useful:
