      Welcome to the party

      Windows 8.1 is suffering from SFC issue since WMF 5.1 was released two years ago

      BTW, this Windows 10 issue has nothing to do with Definitions, it’s just internal PS cmdlets bug

      I had this *exact* issue yesterday.
      Had file corruption, possibly while fiddling with overclocking.
      Several programs would no longer work.
      sfc /scannow found Windows Defender / Powershell corruption which it couldn’t fix.

      Fortunately I had an image of my boot drive that was only 9 days old. All good now.

        How many servers and workstations do you have in your organization?

      From the “Bleeping Computers” article:

       

      Some users have reported being able to fix the error by running the following DISM commands:

      DISM /Online /Cleanup-Image /CheckHealth
      DISM /Online /Cleanup-Image /ScanHealth
      DISM /Online /Cleanup-Image /RestoreHealth
      For those who do not wish to use these commands, you can wait for Microsoft ro resolve the issue.

      It still works.  Just follow the rules of troubleshooting.

      The image in my previous post isn’t very legible.  I ran sfc /scannow and got the “can’t fix ’em” result.  I then ran dism /online /cleanup-image /restorehealth and let it complete.  I never use the “/checkhealth” or “/scanhealth” switches.  The “/restorehealth” switch does the whole ball of wax in one fell swoop.

      I ran sfc /scannow again, and it completed successfully, “found some corrupted files and fixed ’em”.

      FWIW, I have a few commandlets ready to use when needed.

      A couple of years ago, in notepad, I typed

      dism /online /cleanup-image /restorehealth

      and then saved it as “Restore Health.cmd” on my Desktop.  I can right-click it and select “Run as administrator” and it opens a Command Prompt, runs to completion, then exits.

      In the example in my illegible screen shot up above, I right-clicked, selected “Edit”, copied the text, pasted it into the already-open Command Prompt, and hit Enter.

        Did the “followed by” sfc state that it found corruption?

      I’m running SFC /SCANNOW at this time and so far at 95%.  I start it from Control Panel, Command Prompt with as Administrator.  Oops, forgot, it’s Windows 10 Version 1903 Build 18362.239.

      I’m on 1809 and so far 2 of my computers had the SFC problem but the DISM cmd fixed both of them. I haven’t gotten to the other 2 computers yet.

      @berton, The SFC runs all the way through but finds errors that it cannot repair which turn out to be Windows Defender problems in the CBS log. The DISM cmd fixes the anomaly.

      Four systems, all Windows 10 Pro x 64. One machine is still on 1809, the other three are on 1903. Cannot duplicate on any. It appears I’m one of the lucky ones. lol

      Has anyone run the SFC Scannow on a system with the most current Defender definitions?

      Perhaps MS fixed the problem?

      Yesterday, the Deployment Image Servicing and Management tool was failing on the B side of my dual boot. The error code it was throwing was dot Net 3.5 related. I did a repair/reinstall to no avail, and decided to wait it out. After all, nothing else was affected, Windows was operating normally.

      This morning I rebooted to the B side and checked for Updates. I got KB4506991 installed (Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903), then tried dism /online /cleanup-image /restorehealth, and it completed successfully.

      Can someone tell me if me having the exact issues from this post but Windows 7 Professional could be related to the Defender definitions. No matter what I do this Security Update for SQL Server 20104 will not go through. I have spent hours and hours on this. I do however get the exact SFC /Scannow error but the log files do not show me what is corrupt and it can’t fix. Other updates seem to be fine, i.e the quarterly roolup is fine

      Any help with be so appreciated. I am very new to this.

        I assume you are running Defender instead of MSE. Simple way to find out is to run the CMD as an administrator DISM /Online /Cleanup-Image /RestoreHealth then run SFC again.
