Solved Sfc /scannow will not run

[mike2111]

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.

Try an in-place repair:
Download the media creation tool, double click to run this & choose to upgrade now.

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?

 

[Goddess-Bastet]

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.

Thanks - will do.

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

 

[Goddess-Bastet]

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

 

[mike2111]

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.

 

[Couriant]

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

 

[mike2111]

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.

 

[DR.M]

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.

 

[Couriant]

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.

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?
