SFC /scannow > Recurrent finding & repair of corrupt files

I have just finished a Win11 repair install, ran a few reg edits suggested by Brink tutorials, nothing unusual. I run SFC /scannow, and I get this:
"Windows Resource Protection found corrupt files and successfully repaired them."

Before the repair install, it took three or four runs of SFC to come up clear. After the repair install, it takes only one repeat. That's an improvement. But I was still surprised to see any problems at all, so promptly after the repair install.

I ran the repair install because that behavior kept recurring - three or four runs of SFC, even when retrying on the same day. I guess I should interpret the situation as having a troubled installation, but not as troubled as it was before?

Do you have any Windows customizations done to your system as that may trigger repeat SFC errors. Your best bet is to see if you can find the errors in the CBS log file. I know it's a pain to go through but it might help you pin point the problem. One customization that triggers an SFC error every single time for me is using a custom Windows startup sound. SFC flags that sound file and changes it back to the default barely audible sound file.

It sounds like your SSD/HDD has some Bad Sectors and may be starting to fail.

If it comes out Good, you can run a Surface Scan/View or Repair Bad Sectors. If it comes up with any red boxes, it needs to be replaced.

@FrancoDT: per SuperUser, I ran findstr /c:"[SR]" D:\Current\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" (D:\Current being where I saved a copy of CBS.log). The resulting sfcdetails.txt file wasn't immediately informative to me. I decided to review its lines via Excel.

I opened CBS.log in Excel (fixed width columns); added a sequentially numbered Index column to preserve the original row order; stripped out the codes (e.g., 000000a5) that prevented some rows from sorting by text content (using e.g., MID); sorted by that trimmed descriptive text column; flagged the rows containing seemingly innocuous or redundant material; resorted by Index; filtered out the flagged rows; and reviewed what was left. The Excel procedure helped me to see what I might have noticed in the sfcdetails.txt file, if I'd been more recently reminded of how it works.

The problem seems to be that I deleted unwanted, Windows-installed folders in the Start menu (e.g., Administrative Tools, Windows PowerShell). In Windows 10, I found that such deletion caused problems. But in Windows 11, a prior discussion in this forum informed me that deleting those folders caused no harm. That may be right - the repairs noted in CBS.log may be inconsequential - but deletion did trigger the aforementioned errors and repairs.

It seems I may be better advised to proceed as in Win10: move those unwanted folders to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\_Incoming (via e.g., a scheduled HOURLY.BAT), where I store newly created Start menu icons and folders that I haven't yet gotten around to arranging as desired.

(Incidentally, I wonder if you could fix your startup sound by invoking it in STARTUP.BAT.)

The other suggestions offered above may also be legit. I will consider them next, if I'm still getting errors after applying this fix.

When available please update the progress with post #2.

Wow, that's an amazing batch file. Referring, there, to that TuneUp download. Includes characters in non-English languages - Chinese, maybe?

It would be a challenge - it might take me a week - to figure out what it does.

Since I don't need it, and since they tell me not to be overly trusting, I'll hesitate. But thanks again for the suggestion.

It runs scannow and restorehealth in the background while doing other things and has instructions with a completion popup.

It also produces a text of any problems running scannow.
