SFC Scannow will not start

Question

Windows10 Pro 21H1

I am trying run SFC /Scannow and it returns Windows Resource Protection could not start the repair service.

I suspect some corruption. DSIM cleanup-image and restore health did complete

This is on a system that has just been refreshed with new MB and Intel core 10 i5.

How do I get SFC to launch?

Answer 1

Microsoft Windows 10 Pro Version 21H1 (OS Build 19043.2006)

First scannow:

Windows Resource Protection could not start the repair service.

Deployment Image Servicing and Management tool
Version: 10.0.19041.844

Image Version: 10.0.19043.2006

The restore operation completed successfully.

The operation completed successfully.

Second scannow:

The problems related to scannow were not able to be fixed running restorehealth.

Answer 5

Hi John,

Please try below-mentioned troubleshooting steps.

Clear/remove all temporary files from the temp folder.
Perform disk cleanup.
Remove/uninstall unnecessary apps from programs and features.
Scan the PC using Windows Defender.
Check if the machine is connected to a domain network or not. If yes, try to disable or remove domain applications/VPN.
Perform a clean boot and try performing sfc scan.
Try restoring the PC using the previous restore point. (If applicable)
Repair the machine using system recovery. (If applicable, provided you should know how to do that)

To run a SFC scan using cmd 'administrator'.

Type ‘cmd’ in the search box and perform a right click on it and then left click on ‘run as administrator’.
then type “net user administrator /active:yes” then hit ‘enter’.
Restart your machine
Login using ‘Administrator’ account in Windows 10. It takes no password, would let you in, without a password.
Type ‘cmd’ in the search box and perform a right click on it and then left click on ‘run as administrator’.
This time type 'sfc /scannow and hit enter.

If this works out, kindly update on this thread.

Regards,
