A Windows 10 update will not install and the computer sometimes takes several minutes to shut down. I tried to run sfc /scannow but it would not run; I tried two dism runs and they found a problem. I tried sfc again but it still would not run. I have attached the cmd message and tried to attach the log file but it was too big at 12 MB. Any comments as to how to resolve the issue. I wish to install the May 2020 upgrade but need this problem sorting first. Otherwise the computer works perfectly.

Thanks; have downloaded the tool and will upgrade next week - I have important zoom meetings this week and do not want anything to go wrong - will this cure the scannow problem as the fault probably not within windows?

It will repair Windows while keeping your personal files & programs so it should fix the sfc/scan now problem.

Assuming you are running CMD in admin mode when you got those errors:

From a Microsoft post, try this:
  1. Select Start, and type CMD.
  2. Right-click Command Prompt; then, choose Run as administrator.
  3. If prompted, enter a username and password that grants admin rights to the computer.
  4. Type sc config trustedinstaller start= auto; then, press Enter. You should get a SUCCESS message.
  5. Next, type net start trustedinstaller; then, press Enter. You should receive a message that the service was started.
  6. Try the sfc /scannow command again.

Would not work - "Windows Resource Protection could not start the repair service." - after following the three actions.

Was this with the in-place repair or with Couriant’s suggestion?
Have you tried the in-place repair?

This was running the three procedures in Couriant's post above. I am reluctant to update Windows before fixing the sfc problem as I fear that the installation might fail like the latest update to the 1909 edition, and the computer be unusable, although I would make a macrium image first, just in case. I believe the sfc problem is deeper in the computer than the Windows GUI. By in-place repair do you mean the media creation tool method?

If you want me to move your thread in the Malware Removal Forum, I will ask for it. There, we can run several tools to check the computer mainly for malware and then suggest any other solutions if needed.

OK, it does appear to be some kind of corruption that is beyond the fix of DSIM/SFC. I can move it to Malware to make sure it's not related to that. After that, then personally I would recommend a clean install of Windows (after backing up your data of course)

Small side note: the tool you used for getting your computer information is old and has been replaced by this TSG System Information Tool

Thanks, I will run Malwarebytes. By clean install you presumably mean deleting programs and data. With 104 installed programs that is a daunting task, as is even cutting it down to about 30.

I wouldn't recommend a clean install before trying any other means to fix the problem. That's why I suggested about removing the thread in the Malware Removal Forum.

No I meant a clean install as in a wipe of the OS and install the newest version of Windows 10. But this is the last resort, nuke option.

THere are other things that MalwareBytes may not pick up. I would suggest getting this moved (which I can do) to the malware forum to get a full check up.

Yes you download the media creation tool, run this & choose to upgrade now.
This will also fix the sfc & DISM problems.
If the 1909 update failed when you tried this how long ago was this & has there been any Windows updates since?
