How to Fix “Windows Resource Protection Could Not Perform the Requested Operation”

The “windows resource protection could not perform the requested operation” error appears when you run the System File Checker (SFC) command in the Command Prompt. The SFC command is generally used to scan and fix various underlying issues within the computer that cause it to crash or not perform certain functions. 

If users are running into this error and cannot perform the SFC program, It will be difficult to point out and recover corrupted system files, responsible for causing system malfunction. And to fix this problem, users will have to perform various troubleshooting steps to fix the problem.

[Solved] Windows Resource Protection Could Not Perform the Requested Operation

What is Windows Resource Protection?

Windows Resource Protection is responsible for keeping the system files intact. In case something tries to modify the system files or registry keys, this feature would replace the modified files with the original file saved in the cache in order to keep the files safe and operational.

System File Checker (SFC) is a vital part of Windows Resource Protection. Sometimes when a user tries to run SFC commands on their computer, the Windows Resource Protection prevents it to avoid running into system errors. 

Causes of Windows Resource Protection Could Not Perform the Requested Operation

There are a lot of moving parts on your computer and any little glitch could lead to this issue. The following are the most common causes that may lead to this problem. 

  • Malware
  • Not Using Elevated Command Prompt
  • Conflicting Applications
  • Corrupt OS Files

Fixes for Windows Resource Protection Could Not Perform the Requested Operation 

This error is easy to troubleshoot and won’t take up much of your time. Try the following fixes and hopefully, you will be able to run a system file checker on your computer. 


Since the SFC command isn’t working on your computer, using the DISM command is the next best thing. As it will scan the computer and repair any underlying issues on the disk that might be leading to this problem. To use the DISM tool to make the repairs on your computer, perform the following functions:

1- Open Command Prompt (Run as Administrator).

2- Type the command:

DISM /Online /Cleanup-Image /RestoreHealth


The process will begin and it may take a few minutes to complete. Once it is done, reboot the computer and then try running the SFC command in the CMD. If the error persists, keep on reading. 


Corrupted OS files may be causing this issue and in such a case, run a disk scan on your computer. This will scan the hard disk for any underlying issues that could be leading to this issue and fix them. To run a disk scan on your computer, follow these instructions:

1- Press start and type ‘CMD’, right-click on it, and press ‘Run as Administrator.’

2- Type this command and press enter:

chkdsk C: /r


3- Type ‘Y’ to confirm the progress and press Enter.

4- Reboot the computer.

Upon boot up, the computer would scan the drive for bad sectors, errors and recover any of the files on such sectors if possible. This process is quite lengthy and may take up more than an hour. Be patient and let the process run its course. Shutting the computer down during this process could lead to other issues.  

Running System File Checker in Safe Mode 

A simple method that works for many people is to run the system file checker command in safe mode. This is because when you log in through the safe mode, there won’t be any 3rd party conflicting files that could be preventing the command to run. To run the computer in safe mode, perform these steps:

1- Press ‘Windows + R’ and type “msconfig” to open the “System Configuration” menu.

2- Navigate to the ‘Boot’ tab.

3- Check the box for “Safe Mode” and press Apply.


4- Reboot the computer. 

Once the computer has booted in the safe mode, open CMD with admin privileges. 

1- Run this command:

sfc /scannow


2- Wait for the process to finish. 

3- Go back to the “System Configuration” menu, click on the boot tab and uncheck the box for safe mode.

4- Restart the computer to normal startup. 

Perform a Clean Boot 

Preventing all the 3rd-party applications to stop and performing a clean boot could also solve the issue for you and fix this error. To perform a clean boot, follow these steps:

1- Press ‘Control + Shift + Esc’ to open task manager

2- Navigate to the ‘Start Up’ tab and disable all the services except Microsoft services. 


3- Reboot the computer and then try to run the SFC command.

To perform a clean boot on Windows 7, the process is a little different. If you’re a Windows 7 user, follow these steps to disable all the 3rd-party applications on startup:

  1. Press ‘Windows + R’ and type ‘msconfig’ and press Enter.
  2. Go to the ‘Start Up’ tab and uncheck the box for all the 3rd-party applications.
  3. Reboot the computer and run the SFC command through the command prompt.
