Windows 10: SFC failure to complete

As part of my effort to cure problems with booting I have been trying to run SFC/SCANNOW but it fails every time with a notice that 'Resource protection cannot carry out the command', usually about half way through but recently after it after the scan had reached 95%. How can I repair it?

:)

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.


Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

sfc /scannow will not complete- stops at 73%

Hello,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and appreciate the troubleshooting methods performed to resolve the issue on your own.

DNSAPI.dll is a Windows DLL file. DLL is the abbreviation for
Dynamic Link Library. DLL files are needed by programs or web browser extensions, because they contain program code, data, and resources.
DNSAPI.dll is located in the C:\Windows\System32 folder.

I suggest you to try running SFC scan again and check if the scan gets stuck at 73%. If it happens, I suggest you to perform
DISM scan by following the steps below and check if the issue is resolved.

Windows corruption errors may prevent Windows updates and service packs from installing. For example, an update might not install if a system file is damaged. The
DISM scan or System Update Readiness tool may help you to fix some Windows corruption errors.

Step 1: Open an Administrator command prompt
window by

• 
  Press Windows logo + X keys on the keyboard and select
  Command Prompt (Admin) option.
  
• 
  Click on Yes and continue. Provide administrator password if prompted.
  
• 
  Check if it says Administrator: Command Prompt at the top of the command prompt window.
  

Step 2: Type the following commands in the
CMD Prompt:

Dism.exe /online /cleanup-image /scanhealth

Dism.exe /online /cleanup-image /restorehealth

After completing DISM scan, I suggest you to perform
SFC scan on the computer and check if the issue is resolved.
